We will be traveling with our daughter and her two daughters, 18 & 16 the end of June first week of July 2023. Looking for tour suggestions, etc. My husband and I are 74 and this will be the first international trip for all of us so we will need a lot of help.

What sort of tours are you thinking of? London is about the easiest city anywhere to explore independently. Or are you asking about tours outside London?? What sorts of things interest you.

If you are at all in to gardens -- the Hampton Court Palace Flower Festival runs July 4-9.

Look into London Walks (walks.com) for interesting walking tours. We have gone on several, all informative, interesting, and suitable for all ages.

What a great place to go. So much to see, depending on everyone's interests. I'd consider some DVD/streaming programs like Rick Steves to whet your appetites and start the research.

We start out in new cities with a hop on and off tour that hits the highlights and then return to what looks interesting--The Tower, Westminster (Abbey and Houses of Parliament), and so forth.

St. Paul's and The City; a walk across a bridge to the south side, the London Eye (amazing views over London), and more.

London Taxis are great! We use the Tube a lot to get around but with a group a cab could make more sense outside of rush hour.

Several boat tours along the Thames stop at key points (see above) could make for a break from walking, taxi, or bus tours--If I recall correctly they stop at Westminster, Greenwich, and other points. Check the schedule as some take quite a while to make the whole route; we avoid those with meals.

British Museum and Victoria and Albert Museum for those so inclined; Harrod's for the shopping experience.

Churchill War Rooms for historical interest, Kew Gardens for horticultural interest.

Theatre! Great options and (IME) cheap tix.

We like Fortnum and Mason for an afternoon tea, but there are swankier places if desired.

Have a great time!

Wonderful way to start international travel and with family is even better! London is fun and easy to navigate with things to interest everyone.
A few questions.
Exactly how many full days will you have on the ground, not counting arrival or departure days?
Have you booked flights already? Asking this because there might be some suggestions for a slightly expanded itinerary if your flights are not already set in stone.
Do any of you have any specific interests such as Art, History, castles, music, etc? Do any of you have any interests specifically related to England such as Authors like Jane Austen or books like Harry Potter or places like Stonehenge?

Get everyone (if you can) working in advance on understanding the public transport system. There are plenty of useful how-to videos on YouTube, plus the official website:

(Important tip - you do not need to buy tickets for transport before leaving home, all that's easily dealt with once you're here)

I usually start with Rick Steves' guidebooks, although there are other books that are great, too. The guidebook will explain quite a bit about the basics of travel in London and nearby and is a good place to start with planning. Trip reports written here by people who have recently traveled can give you great tips and ideas, restaurant suggestions, etc. You already have some great suggestions above and posters here are happy to answer questions. How exciting to be planning this trip!

Forget the hop-on bus. It will be crowded and likely to get stuck in traffic. The fastest way around London is the tube, if you want a slower trip with scenery ride one of the regular double decker buses sitting up top. Use PatrickLondon's links and you will have no trouble getting around. Rick Steves is fine for first-timers, but you might borrow some other guides from the library - I like the "picture" guides (Insight, DK) for initial planning.

What do people in your group want to see? Castles, mansions, museums, gardens, markets, theater, shops, etc.? My absolutely favorite sight in London is the V&A, which also has gorgeous tea rooms where you can get lunch or a scone and clotted cream for a lot less than a set afternoon tea. https://www.vam.ac.uk/south-kensington

Besides the tours give yourself some time to just wander around. I've been going to London for years. I stay at a B&B in Chelsea now and often just wander around the neighborhood not planning to see anything particular. Try a walk along the Thames between Westminster Bridge and Tower Bridge. South side of the river is best. Go early in the morning before the crowds hit. I'm into photography and like the night scenes along the river.

Most of these photos were taken in the morning.

Just relax for a day.

Just getting back on my trip. I do have the air booked, so we have 6 full days not including travel days.
We are looking at staying as close to Victoria Station as possible, we were told this is where tours leave from. Looking at the Comfort Inn as the price is in my budget. Anyone have any experience with that hotel?

Tours around London mostly, we do want to go to:
Stonehenge-Windsor Castle-Bath
Tower of London - Changing of the Guard - Boat Ride
British Museum
Churchill War Rooms - Westminster Abbey - Big Ben
Buckingham Palace
Warwick Castle
Tower of London - Crown Jewels - Beefeater
Imperial War Museum
Harrod's
Harry Potter - Warner Bros

Is there an app for London Taxi's like Uber has?

Most of those can be done easily on your own. Stonehenge-Windsor-Bath on the same day is too much. You might look at this: https://www.walks.com/

No idea about taxis, I use buses and the tube.

MikeS, your night photos are stunning!

It is probably not silly to take a tour to Warwick Castle, it's a fair way from London. You have a very big wish list for six days, you might have to cull some of those sights. Things I think you can do on your own:

*Tower of London - Changing of the Guard - Boat Ride (you mention Tower of London twice)
*British Museum
*Churchill War Rooms - Westminster Abbey - Big Ben
*Buckingham Palace
*Imperial War Museum
*Harrod's

So for none of these do you need a tour, they're all things you can do in London on your own. For Harry Potter / Warner Bros I think there is a tour (although I've never done it). For most things you could budget half a day. However, for me the British Museum could be a whole day event, others may disagree.

The only tours that would make any sense from the list are to Bath/Stonehenge and to Warwick . . . but with just 6 days on the ground you'd be rushed to squeeze in one out-of-town day trip let alone two,

Warner Bros./HP studio is easily done on your own -- do pre-book the studio tickets.

"Tower of London - Changing of the Guard - Boat Ride". By including those three together i suspect you have found some commercial tour that lumps them together -- Please no! The ONLY way that could possibly work is to hit the Palace in the morning, then after lunch take a boat down river to the Tower. Just a nasty plan all around.

Do the Tower of London on your own. It will take about half a day and you want to do it first thing in the morning. Walk past Buckingham Palace -- take 5 minutes -- forget about the Guard Change. "Tower of London - Crown Jewels - Beefeater" That is what you see when doing it on your own -- why pay a middle man and be on their schedule??

There likely are -- I've never used one though. You simply stand on the pavement (sidewalk) and flag down the next one you see with the yellow TAXI light on the roof illuminated.

Victoria Station is a central location -- but there are a whole lot of other good/great neighborhoods. I wouldn't pick a hotel simply because it is near Victoria Coach Station (since at most you'd be doing a tour out of there - one day)

Forgot to mention in my prior post -- I'd definitely consider no out of town day trips other then Warner Brothers. The other two places you might want to visit as sort of half day trips from central London (on your own - no tour required) are either Windsor Castle or Hampton Court Palace.

If you are a first timer I think you might need to do some reading of guide books and websites. Even though I am Australian and Rick Steves is not someone from our TV screens, he has a lot of free stuff on his website that you can take as good advice for many European destinations including the UK. He actually also gives a lot of advice regards packing, currencies, and other travel skills that could be very helpful for you, so do look him up. Also, you local library might have some guide books that can help you plan your trip (including maps, which will help you group attractions near each other and see them in the most logical way).

I agree with not needing to book expensive tours for things you can do on your own. Save your money for enjoying fun times in London! Rick Steves' book will give you most of the practical information you need. Your hotel should also be able to assist with you with questions, like where is the underground station and how is it best to get from A to B? For four of you, taking taxis to most places might make good sense. You can do this!

Skip the Changing of the Guard - it really isn't that interesting or save it on the "if we have time" list. I wasn't that impressed with the boat ride on the Thames but I see Westminster Abbey isn't in your list - I'd try to fit that in.

Also, try to save a bit of energy for seeing a play or two. London is a great theatre town.

Yes cull changing the guard. So much more to see than that.
