As Aime 2000 is a huge hotel with many corridors, you can actually use them as a partying spot. The party usually starts when somebody sits in front of the room and smokes (not to smoke in the room). More people come and join and the party begins.
You can start partying just after finishing skiing. Just sit on the bank in front of your hotel room (just in case you get tired), bring some beer and the party goes on.
Dress Code: Skiing clothes and ski/snowboard boots.
Hotel room is a good place for preparty. The rooms in French Alps are usually very small but this time it was even 30 people partying in one room. You need to organize it somehow if you go for a trip with 40 friends.
