We'll be in Orlando for a trade show mid December and was thinking about doing Discovery Cove. However, I know the weather is not always great that time of year. Since it's off season, do you think it's possible to make a reservation maybe a day or two before when I know what the weather will be like. It's so expensive, I would hate to go on a rainy 50 degree day. I wouldn't think they'd be sold out in advance for then, but maybe I'm wrong.
