Checkout the island south of green can 53. You can enter the anchorage from the east or west. I've anchored there while going from Pensacola to Panama City. Good depth and holding. Check it out on Google Earth, the entrance to the west isnt charted correctly, but easily navigated visually.
As for the show, anchor off the Quietwater board walk in the sound. The mass amount of anchored boats will be your indicator
