Personally, I think it is important during the winter to have a hot tub to warm up in, so I look for hotels with nice, heated swimming pools and hot tubs. This winter, some resorts have closed their hot tubs due to covid19, so if pools are important since the water parks have closed, make sure to call and find out the status and new rules. Things could change between now and December also.
Wyndham Bonnet Creek had a great selection of pools, hot tubs and lazy rivers which may be a good alternative this winter.
Aquatica is my favorite water park, but if the air temperature is low, it is very difficult to warm up there. Sometimes the water in the showers is cold, so you can’t rely on them to warm you up. They heat the water in the pools to about 86 degrees.
