Does This Sound Like A Fun 12th Birthday Party..........?

My sister is turning 12 in July, I'm planning her party for her. What I have so far is to take her & 5 friends out to get their nails & toes done, eat dinner at a restaurant, come home make ice cream sundaes, have them creat their own goody bag (I'm going to set up a station with a bunch of nail polish lipgloss ect and they can pick and choose what they want to put in their goody bag, then i would put on a movie and just let them do whatever. They will be sleeping over our house. Any ideas or suggestions????
