We are wrapping up spring break which involved some adventure. We learned that our kids don't like to do a lot of walking. They need at least half a day at the pool or to relax. That being said, we would still like to try Europe in June. Our youngest is 4, oldest is 9. They are not the most active kids in the world but are curious and creative. What would you pick for your first trip to Europe with kids? We have about 2 weeks. Thanks!
