What is the temperature like on a cruise in Jan, Feb? I'd like to go in Sept this year, but DS won't be 3 until Jan 20th and wouldn't be able to go to the kids club (only flounders). I feel like he'd be to "old" for flounders, so wondering about waiting until he turns 3 to go on a cruise. Is it warm enough in Jan/Feb to swim at the beaches, etc? Or is it pretty chilly? If its too cold we'll wait to go when its warm enough, as that is half the fun for us. So if it IS too cold in Jan/Feb, when would you go so that you could comfortably swim?
