What is a reasonable budget for a bachelorette party?

Im new at planning something like this and the best man just informed me that the groomsmen are expecting to pay 750-900 dollars each for a weekend in Vegas. I dont think the girls want to go in debt considering we have dresses, hair, makeup, and also the bridal party to pay for and most of us are still students. I can save up and I want to make it memorable but Im a little lost on how to start planning and what kind of budget I should be aiming for...
