Taking my 13 year old to Europe to encourage travel and learning...suggestions?

[soliloquy]

I've booked a trip to Europe for Spring 2017. My husband is staying home unfortunately because he can't take that much time off of work. I'm taking my teenage son and my teenage brother (he was a late surprise for my mum). I've been doing a lot of research to try and pick the best places to go. I really want to bring history to life for them. I have a travel agent and we'll have tour guides so we won't be going to all these places alone. However, I have to solidify our itinerary sooner rather than later so I can obtain accurate pricing. I want to do a kind of whirlwind tour of all the places they've been studying in history, art, and social studies. My brother is in his junior year and I really want to encourage both of them to study abroad when they have the opportunity. I figured the best way to do this is to take away some of the anxiety of traveling across the pond. I'm still working on our itinerary but so far I'm working with a travel agent to visit what I consider to be all the highlights. This is what's on the agenda.

If you have any suggestions or comments, that'd be awesome!
