Sleepover Birthday Party--Need Ideas!

Heyy
My best friend and I are having a double birthday party in one week. Here`s our schedule so far.
4:30- Get dropped off at my house
5:15- Limo picks us up and we go to the mall for a scavenger hunt.
6:30- Go back to my house for dinner--pizza.
7:00- Spa Night
8:00- Cake and gifts
8:45- Movie--chick flick of course
10:45- Games like M.A.S.H and truth or dare
11:30- Start winding down and just girl talk and get in sleeping bags
10:15 am- Pick up

Everyone at the party will be twelve. Please help give me some ideas for games to fill in the gaps!
Thanks!
