In the public garage or on the street. If you have dinner at some of the restaurants, see if they valet and will validate your ticket.
What do you mean by economical? if you mean you don't want to take a chance of getting your car broken into or stolen then I think the most economical way to go is to pay for a car garage where your car can be safe
If you get there early parking garage was $10. Later, closer to show time, it was $15.
