Going to the Jimmy Buffett show. What time does the parking lot open?

4:00pm

I think most shows open at 5:30. Only enter off of Main Street I repeat only enter off of Main Street unless you are there 3 hours early to go in from the back entrance off of Otay.

4pm

You can start tailgating around 4:

4pm but ride (uber or lyft) so you don't fight for parking. In and out safe even if you had a few drinks.
