We've never experienced frost at this time of year, but it certainly does get cooler, especially in the evenings. We mostly wore shorts or jeans (on non sunny days) with t shirts, and fleeces/hoodies in the evenings. Best advice is to pack a little of everything. The great thing about this time of year is that the parks tend to be much quieter and the whole holiday takes on a slower pace. Hope you have a great time.
