Agree that Sundays on Mullet Bay bring lots of people, with many locals. It's a great beach with good snorkeling, but do it a different day of the week when less crowded. I would suggest happy hour at Sunset Bar and Grill after 4:00 on Sunday. It's a vibrant, happening place at that time, but not too crazy cuz cruise ship guests are gone. Food is pretty good too if you want to get an appetizer or meal with your drinks.
