Need a good snorkel excursion in Nassau - short trip, not long

[BuckeyeMark]

We aren't hard core snorkelers. Would like something with a short boat ride (DW can get seasick), some fun snorkeling and then back home to do some other things.  A five hour trip out to the perfect snorkel spot with three hours in the water there isn't in the cards for us. Recommendations for short but good trips? 

Anybody done Stuart's Cove shark snorkel?  That looks very cool!

We brought our own gear and snorkeled right off Junkanoo beach. It was okay. My husband enjoyed it more than I did.  We walked around Nassau for a couple hours first, then spent a couple hours on the beach, then headed back to the ship early.
