Steve posts the Boobs Cruise dates about a month in advance. We have gone on quite a few and they are well worth it. Like everyone else is saying, it's what you want to make of it.. and of course the saying is "No one knows you and no one gives a shit". We're going back on November 20 and can't wait...
You didn't mention where you are from. Judy and I would find it too cold in January to go in the pool. We shiver when it drops in the low 60's but if your from Canada you may love it. We have been in May and October this year. The weather was nice. May is better than October in our opinion. People are great whenever you go. There are some slower times of the year and January I believe is one of them due to the cool weather as compared to the rest of the year. Summer is HOT! Plan accordingly.
We are from California. The 411 I can find regarding the average temps is telling me the highs are 75 which is ok but any lower would be no bueno! Do they heat the pool? Any idea about that temp? We just discovered this adult playground and don't want to wait until May to check it out! We are definitely pool-beach vacationers and the sightseeing for us will be at those places. Non-pool weather would definitely not be good for us. Now we are on the fence about the trip at end of Jan.....may have to back it up.
Weather is hit or miss in January, been to Cancun 3 times in January and have had rain a few days each time. It was still better than the weather in Northern Alberta in January. I wouldn't let the weather hold you back, Temptation is a blast rain or shine.
The weather will likely be warm enough to hit the pool. Don't plan on sweating much. We are from STL, and it feels great to us.
I was there last year the first week in Feb. Julie and I will be there 2-8 this feb. Sort of a good time to go cause you miss the spring breakers later into the month and early March. It rained one day for the better part of one morning, that said the rest of the days were perfect Mid 70's.
