Thanks to all for your advice. We are getting so eager. We have only seen good reports on the Mayan Princess. We were lucky to be able to schedule a last minute trip to replace a canceled trip to Cozumel.
We are finishing choosing which dive gear today. We always wear full suits of some kind. We are going to pack our plain lycras and our fleece-lined and some 0.5mil skins. That way we can double up if need be. If you put the fleece-lined lycra over the plain lycra, I have found that to comfortable when others are wearing 3 mil. We have never been to that area in the winter before. I am now wishing we had taken the time to buy some 3 mil suits. Up here in WV, USA, we always need at least 5mil or 7mil So we have them, but they will be too much.
Thanks to all for the replys!
