It's the Eastern Caribbean. Lots of ports so I don't expect to be on the ship much. From my scribbled notes; St Martin, Cazumel, Aruba, Carico, Nasa, PR.
I'm not a cloud chaser so that won't be a problem. I do like the shower cap idea though. I'm traveling with a relative so it won't be a smoking room. I can't stand the smell of those anyway. I didn't want to have to drag extra charging supplies if not needed.
I have to do some research. I've never been on one and am wondering how you go snorkeling, shopping and zip-lining in one day off the boat. What do you do with your stuff??
