Yep!! Might even offer the cruise as a Day Excursion. Go on cruise, go swimming for awhile, come back get refreshened up, relax for a couple of hrs, then BCD activities, and evening cruise to finish.
to first rent a couple of different boats for a day each to get a feel of what YOU really like, opinions are like....well, you get the point. It is expensive to rent boats BUT much less expensive than buying one you are not happy with (kind of like women, you can hire one to test it out but once you're married...)
