It depends on how many girls you choose to invite. When my daughter turned 11, we hired a limo service to go to each girls house to personally pick them up and then he drove them around for a while so they could feel special and important.
Afterwards, we picked up pizza, went back home for a pizza, craft and sleepover party.
At 12, we rented a suite at the Marriott in the Shops of Legacy. We only had 6 girls total. We went to a nice dinner, they swam in the pool, had room service for dessert and a nice breakfast the next morning. They loved this outing.
If she is still into the games, etc. Dave and Busters at Stonebriar has a room you can rent out. We did that 1 year and they had a buffet, game cards and sleepover.
