Well, between yours and mine, we know there will be at least 2 families there! From what I have read this time of year is slow. How slow? I don't know, but I am hoping for the best. We also have a water park day built into our schedule, and I was wondering the same thing. We went to the NickHotel last weekend, and although the pools were warm and the weather was very warm, the water from the sprayers, slides and showers all over the slide area was cold. So if the sun went behind the clouds, or at night, it was a little chilly. At night, we only went on a few slides before hanging it up. I have read that in December, you should pack for all kinds of weather. I guess we will just decide when we are there if it fits into the picture. We have plenty of park passes, and it wouldn't hurt my feelings to have an extra day at the MK!!
Have a great trip, maybe we will bump into each other!
