How many queens are you able to realistically meet at Drag Con?

Going for one day to Drag Con LA next month and have the VIP passes. If you've been, how long do the VIP lines usually take to get through? How many queens is it realistic to expect to meet and still have a bit of time to go to panels and such? We are planning on meeting some of the heavy hitters like Bianca, Alaska, Jimbo, Tia, and season 16 girls, but also some less popular ones.
