Open Question: I’m looking to plan an absolutely AMAZING sweet 16 birthday party for my daughter. What are some good ideas?

We've always gone big for my kids birthdays. We've done clowns, magicians, ponies (all in separate years). What is something that would be really over the top to do for her 16th. We were thinking about going to a racetrack and letting her race, but I think we're too late to schedule that. Thanks for your help. 49 seconds ago - 3 days left to answer.
