Pity you are missing out on Cornwall and Yorkshire. If I had to choose between Bristol and Devon I'd choose Devon and Exeter.

Wales, well north and central Wales is lovely from a walking point of view, the south can be a little depressing. Cardiff, maybe you have family there, there has to be a reason for the visit.

Away from the motorway system you will find that travel takes a lot of time (use Google and add 40%), the latest upgrades to the motorway system are fantastic but when they do stop they stop. If you've not driven here then I would search out roundabouts on youtube and train yourselves on how to use them and maybe a few other road types. The UK is the world's safest country for driving on but it does not mean that some of our drivers are not plonkers and a fair bit of patience and smilling, waving thanks etc is built into the culture.

The OP says above that she is is from Missouri. The biggest problem is that they want to spend only $100 per night. Yes Premier Inns and Travelodges may offer that in places, but London will always be more than that. You can't plan a tour of the UK on the locations of those hotels as the only Premier Inn in the lakes is in Kendal. You can book that now but the cheapest prices are always non refundable if you don't go, and non changeable if you were to need to change dates. Travel Lodges are in two places, Kendal and Penrith but If you add on food and transport costs, you'll be way above your base costs, particularly with transport. Again you'll have to budget a bit more generously for accommodation as $100 is about £80. Even the British definition of a B&B wil swallow that up depending on location.

You'll have to book trains at least 3 months in advance to get the lowest prices and most walk up prices for inter city trains will make your eyeballs bleed. London to Glasgow on a walk up fare currently is £292 but if you book in advance that comes down to £60.

All in all you need to plan carefully and in advance. It might be tempting to wing it but it will cost you. Arrive at a plan that is doable and doesn't involve back tracking across the country, saving both time and money.

OMG -- I completely missed that. You are not going to find ANYTHING in Edinburgh -- not even a broom closet -- in August anywhere near that. You'd be lucky to find something 4 times that. And except for hostels, I'd be very suspicious of any property in central London charging $100 per night. That is between £75 and £80 depending on the exchange rate on the day. Premier Inns and Travelodges are cheap in a lot of places but not in London and definitely not in Edinburgh in August. As an example - one very well located Travelodge in Edinburgh that one can often get for £50-ish or even a bit less, charges over £200 in mid August . . . and books up months in advance.

OK - more re budget SOME Premier Inns/travelodges in London will meet your budget but several will not. But rates are VERY date specific so you'd want to look at each property individually. For instance County Hall Premier Inn is almost never under £125 and often over £200. Whereas the Covent Garden Travelodge can be £65 one night and £150+ the next.

Also - you are on a $100 per night budget (more in London) but want to go to places like Royal Ascot and Wimbledon. That seems a bit of a contradiction.

And that makes staying in London for a month counter intuitive. Except for Edinburgh, London will be the biggest budget buster so I'd cut my time there way down -- to a week, 10 days tops. (and this is from someone who LOVES London and visits there at least twice a year)

So as I said, premierinn and yha are the solution. Book far out.

Who stays in travelodges? Filthy things

Ibis is also a clean chain.

Outside of London there are B&B an AirBnB.

Edinburgh just goes nuts in August

>>Who stays in travelodges? Filthy things<<

True - in a lot of places they are awful. Not mostly in London though -- most are brand new and most are very clean and several are very central.

I was going to suggest student accommodation (universityrooms.com or lsevacations.com), but checking for next September even those don't have doubles under 100 GBP, never mind USD, in London.

My last visit to London I stayed at an Airbnb, big private room & bath with fridge & microwave in the corner, paid $491 (US$) for a week, all fees included. In Wimbledon in May, very convenient for my purposes and would be in general, close to a tube station. Same room is shown now for $51 a night, that would be plus fees, maybe somewhat more in May. My point, Airbnb has some great bargains even in London and if you're willing to go 15 minutes out of the center by tube you'll find plenty well within your budget. Just spend some time on the site. It can take a while to narrow down the choices but well worth the effort for those of us on a budget. Don't let the naysayers get you down!

airbnb is certainly an option but a place in Wimbledon likely wouldn't be viable for the OP -- not when they want to be there. They want to attend the Tournament so that $491 could be closer to $2000.

casjay: If you DO want to stay outside of the core - and that can make a lot of sense for an extended visit like you plan -- make sure it isn't farther out than zone 3 (zone 1 is mostly central London). Otherwise a lot of the savings will be eaten up with transport costs. Also make sure it is convenient for rail service for all the day trips you want to take.

I was using my stay in Wimbledon more as an example of an Airbnb stay out of the center but still convenient & economical, rather than a suggestion that they should necessarily stay in Wimbledon. But one can always find a reason to not do a thing if one is committed.

http://www.booking.com/Share-UN7VH2 Look at something like this, close to transportation and you could cook a few meals and save. I saw some great places on airbnb but we are only staying three or four nights in June then moving on to Isle of Wight and Portsmouth.

https://www.vrbo.com/8019113ha?adult...ure=2020-08-08 100 USD a night but first two weeks of August, hurry and see if they have the dates you need. I would stay here. There was a guest house for 76.00 a night and a little dark but good price. Just give me dates and I will help you look.

I know -- that is why I posted. >>airbnb is certainly an option<<. AND >>If you DO want to stay outside of the core - and that can make a lot of sense for an extended visit like you plan -- make sure it isn't farther out than zone 3 (zone 1 is mostly central London).

So I certainly wasn't posting any reasons to not use airbnb. Totally to the contrary. I was giving hints how to make it work. But then one can be blind to when someone is actually agreeing with them . . . Can't win for losing.

On that point I agree.

Pembrokshire is a gorgeous part of Wales with a fabulous coastline and sandy beaches.
I love Bristol - it's a great city for cyclists, history (don't miss suspension bridge and docks), architecture (Clifton), galleries (Arnolfini, RWA, home of Banksy), museum, eating, shopping, parks (Clifton Downs, Brandon Hill etc) etc and it's all walkable.
I'm afraid the Lake District could be wet any time of year but as long as you have waterproofs you will love the scenery and you may be lucky with sparkling sunny days.

http://www.booking.com/Share-gSqsVbJ Within your budget but hurry, there aren't many left and this is for the second week of August. Public transportation is good there. It says for two but then shows a twin bed. Hmmm, maybe contact the place directly not through booking.com. I still like the apartment in first EDI link.
