So, yes, we've booked the 1/18 8-night Bahamian out of Galveston using the Kids Sail Free promo. It's not often we get to benefit with "kids" deals with teenage boys...been a long time, actually. Ports include Key West, Castaway Cay, and Port Canaveral/WDW. So far we've only been to Castaway Cay in May & September. We know the water temps in May are pretty dang chilly & in September they're pretty comfortable. Air temps for both of those months are pretty warm to hot. So what about January??? We live in a Gulf coastal town so it's not that big a stretch to go search for knee-length wetsuits if they will be needed. Trying to think this one all the way thru and be prepared!
