Bachlorette party for a 19 year old?

My best friend is 19 years old and so am I. She's getting married next month and I need some bachlorette party/bridal shower ideas. We're thinking Dave and Buster's, a little drinking at home, pedicures, manicures, a personal shower with lots of naughty gifts...stuff like that. I need some ideas that are somewhat inexpensive, but will still make her happy.
