The earlier you get there the more time you have to enjoy. They are always steady, ive never seen anyone turned away
I didn't snorkel but I would recommend you get there early
I went on a Friday morning about 11. They open at 8. I waited 15 minutes because I needed to rent fins. There wasn't a wait if you had all the snorkel gear but I suggest getting anti fog stuff for your goggles. Water was 72 degrees.
