The only time I've been during Jan/Feb was about 10 years ago, and if I remember, the crowds were light and the weather was a bit chilly.
Don't want to hijack the thread, but one of the reasons I've never scheduled a trip during this time is b/c I wonder about the pools. I know they're heated, and I know it's personal preference (I get cold way too easily!), but do many folks swim during Jan/Feb? For my kids, swimming is one of the best things about vacations, and they'd probably go in whether they turned blue or not! Just wondered what other folks usually find re: pools during the winter. Too cold?
