Do you mean like a one day c/o cruise around an island? Or, another c/o destination for a longer stay? Temptations Resort from Cancun has a five-day 'big ship' cruise going in February, 2020. Not exactly clothing optional, but pretty close and totally top free for the ladies. And, they usually make a couple of stops to secluded islands where the option to go in buff occurs. Keep in mind, however that the Temptations clientele is roughly one-third "alternative lifestyle" folks if that is a concern (it shouldn't be). I think they're departing from Tampa this winter, and I'm pretty sure that Grand Cayman is one of their stops. Hope this helps.
