Two weeks or two months, you won't see everything. Granted, the locations will be there in the future but your family situation will change...kids grow up. Do all three but plan very well. Pick the most important sites for all & go from there. Start in Rome, fly to Paris & train to London.

I did the same 3 cites for a honeymoon over 23 years ago. It took us 14 years to get back. Glad we did what we did when we did it. Enjoy the trip with your family NOW!

Since you are all talking about traveling with young teens, maybe you can help me.
We took our daughter on a 3 week trip through Europe when she was 12. We flew into London in July and all she remembers is that it was so hot and humid and she was tired and she hated it. She loved Ireland becasue it was so pleasant there.
Now we are planning a trip to Scotland next July and plan to again fly into London and then proceed to Scotland, where it will be cooler.
This is the only time of year we can coordinate this trip to all go together.
We want to spent 2-3 days in London with our daughter who will be 15 years old. What can we do with her in London to change her mind that it really is a fun, hip place to see? We did all the tourist stuff last time and I am looking for some cool things to do like Portabello Road or Chelsea outdoor markets etc. Clothes shopping would appeal to her, on a limited budget!
It will probably still be totally hot and humid, so maybe you have some ideas?
Also, can anyone recommend places between London and Glascow that might be places of interest to a 15 year old?
Thanks for any help!

hyacinthcourt, you raise a good question, but it is buried at the end of a thread that is different, and that might not get read by those who have the most information on the UK. I would suggest that you post the exact same question in a new thread, indexing it to the United Kingdom when you set up the post.

Here are my initial thoughts: I went to London with my 17yo daughter in March, and we had such a great time that we will return in August at the end of a trip to Scotland. My daughter enjoyed the ethnic food (although we ended up eating more Italian than we really wanted), some of the museums (the dresses at the Victoria and Albert, the Treasures room of the British Library), the London Eye, the shopping - especially the vintage clothing shops - and Portobello Market. Our trip report from the March trip is at: http://fodors.com/forums/threadselec...p;tid=34771547

On our August trip, we will ride the train from Glasgow to London (goes through Edinburgh). We are looking forward to the views from the train. We will stop for an overnight at York, where we will see the Minster, the wall, the Shambles. We are thinking of skipping the Jorvik center. Yorkshire itself sounds wonderful, but we will not have the time to explore. When we reach London, Camden is at the top of her list.

Anyway, I encourage you to repost and I can give you a list of shops that my daughter likes, if that is of interest.
