I'm sure this is after you have travelled, as I noticed I am replying to something posted nearly a month ago, but I LOVE the Sheraton CDG. It has an atrium in the center and a frosted glass floor, which you can see through the floor to see the TGV rail station. It is built into the airport and every room has a good view of all the planes! If you get a 2C view you get to see the 747s from your bedroom! What fun.
