I saw the world premiere of the play "the Gentleman's Guide to Love and Murder". A fantastic play in a fantastic space! It was a little pricey, but worth it. Not to mention all the free things you can do before the play in Balboa Park. Best day of the vacation. Tip- If you come early around 5 o'clock, you can get great parking. Also there are very cheap eats at the expensive Prada restaurant. It's a great restaurant with a great happy hour from 4 to 6.
