We normally go in April, but depending on when value seasons fall next year, it's possible that we may go in Feb or March. However, the major drawbacks to that are that my wife wants to do a beach day and I would like to swim in the pool and go to a waterpark. And I'm not sure if either of us will be able to do that in February. How cold does it generally get in those months? When do the water parks open for the season?
