Thank you everyone. I asked about them "making the sleep" because I have heard they can be strict with UM and that they might treat them like young kids. Since they are young teens, they would probably prefer to stay up. I just wanted to prepare her to listen to the rules and obey.

Her friend plans to use her Finnish passport because they will be traveling to France and Italy during the summer and her parents said that it is less hassle to travel in Europe with it. But my daughter is only American so will only have her US passport.

They are so lucky to have this amazing opportunity and I am excited but also a little scared for my daughter. As this is her first time and I haven't traveled outside of the US in 14 years I want to give her up to date information, not my outdated memories.
