I did the Waverunner excursion at Castaway many years ago. We rode out to a sand bar, spent a little time off the vehicle, enjoying the shallow, clear water of the Bahamas.
I had no prior experience and no motorcycle experience, either. It did not matter. What I learned from it, though (same applies to ATVs) - it is an athletic activity. Look for an excursion that is limited time, not multiple hours. The hardest part for me was crawling into the runner. If you fall off in not-shallow water, you have to pull yourself up onto the back.
Check out excursion sites like Viator to see what sells well (and has good reviews). Nassau does have providers of this. The #1 rated company has this photo of their destination. They go out to Cabbage Beach.
I’m guessing the Wish won’t take you to the Caymans, if it is still doing 3- and 4- night Bahamas cruises?
It was fun flying across the water. Hope you get to someday, also.
