Sleepover Games! Need Help ASAP!

Ok, I`m having a 13th birthday party. There will be 6 girls. 3 12 years olds, 1 13 year old, and 2 8 year olds. It will be a sleepover party at a hotel, so we can`t do a lot of things. There is an indoor pool, a spa, a fitness center, and a hot tub IN THE ROOM! AHH! Anyway, we can`t do anything really loud, or seceritive either. The parents and us have joint rooms. I only have about 3 games so far. But I need MORE! Help me please!
