I hope this isn't too late, but here are a few ideas...mini spa makeover-include facials, mudmask (guaranteed for laughs!)manicures, pedicures. Guests could style each others hair, borrow a book on braiding from the library. Present a samll pack of beauty sample and a bright hair accessory as party favors.
hotel party- rent 2 bedroom room (one for the girls, one for the chaperones. Make sure there is a swimming pool, game room, bring lots of popcorn, sodas, videos, etc- or use room service. Let the maids clean up the next day.
Hope this helps!
