I am looking for any information about going to Aquatica in November. We are doing DC and just found out our ticket now includes entry to Aquatica. We would like to spend at least a few hours there but I am worried about the weather. I know DC's water is heated. Is the water on the slides and pools at Aquatica heated also when the weather is chilly? What kind of crowds should I expect in November, the week of Thanksgiving?
