Backstory: we had an amazing trip to Italy in May/June with the kids (11 and almost 14), went to Rome, Cinque Terre and Florence, with a day to see Pompeii. It was exhausting but so much fun, and now we all have the travel bug (mostly me but I know the kids want to see more places, too). The question is-where to go next? We were all really excited about Italy, but we don't have a spot picked out for the next trip. The kids have mentioned Germany (no specific cities), London and Paris, but I am sure they can get excited about other destinations as well, and I want to keep open to possibilities I may not have considered, like more off-the-beaten path places. Rome, Florence and CT were all quite crowded, but we planned our museum trips well, and didn't have to wait in lines, so it was tolerable. Really, I didn't mind it too much but would also be happy to find less crowded cities. We are restricted in that we have to wait until school is out and the last day is May 18, so I was thinking of going in late May to avoid the worst of the summer heat and crowds.
If any of you have traveled with tweens/teens and found somewhere to be especially awesome, I'd love to hear about it. If this helps, they especially enjoyed: 1) the Coliseum, 2) Cinque Terre, 3) St Peters Basilica 4) Gelato. They did great in museums, as long as that wasn't all we did, but I think the fountains and architecture were equally impressive as the inside art (we all loved seeing David and Botticelli's Venus etc). I had the idea of watching some of RS videos to get ideas, so we will probably do that but I figured I'd ask the experts here since I'm focusing on places that are appealing to kids (while they are still interested in spending time with us lol). And I know there are some seasoned family travelers. Thanks!
