We will be there February 12 - 17th! Last year we were there during Presidents' Week. It was quite cool in the morning, but always warmed up nicely in the afternoon. You have to be prepared because it can be unpredictable at this time of year.
For us, even if it's cool in Florida, it will be WAY better than home - at the moment, the temperature is 6 degrees here in the Detroit area! BRRRR!
