Here is a spa sleepover party for preteen girls: Invitations: MAke invitaions that say something like "_________'s(b-day girl's name)Spa! Appointment reminder. And make it sound like a real appointment reminder for a salon or spa. Don't forget to include the date, time, etc. Send them out a few weeks before the party. Party day: when the guests arrive (no more than 6 is best for this kind of party), around 6:00, treat them to pizza and POP (lots of it!), as well as a fruit tray, chips, etc. After that have a smoothie bar- have many fruits, vanilla ice-cream, juices, etc. set out for the girls,a nd let each girl "create their  own" smoothie. You can even make a game out of it, where the girls each put a sample of their  smoothie in a dixie cup with their name on it, then the judges (parents) will taste test them all and  say who's is best. A prize could be a bottle of nail polish, lipstick, hair accesories, a brush,  whatever! After the smoothies, eat cake and then open presents. After all that is finished (it may be  around 8:00), start your spa treatments! Have different stations set up in a large room such as hair,  nails, make-up, skin, facials, a foot spa (optional, but you can get them at most stres-it's like a foor  bubble bath), etc., and have each guest pick a different partner for each station to do each others manicures, pedicures, facials, hair, make-up, etc. Then, all the girls can get their swim suits on and  go in the hot tub (if you have one). After that, have the girls set up their sleping bags and watch a movie all the girls agree on (it's best to have a few different movies set out so the girls can choose). After the movie (or during), everyone can play truth or dare, or some other game. Try not to wake everyone else up in the house, though. In the morning, have mom make pancakes, or the girls can  all help make them! Provide lots of toppings (chocolate chips, blueberries, strawberries, rasberries,  etc.), and then dig in! Around 10 or 11 the girls should go home, and don't forget a goodie bag for  each of them, including things like make-up samples, brushes, hair accesories, lipstick, nail polish,  etc. Have fun, and be sure to get very pampered!!!!
