Ah, nice just after the holiday. Might still have some left over crowding with heavier crowds on the weekend.
Hollywood studios has nearly consistently closed at 7 since the reopening, so you can probably count on that at least.
Animal kingdom during the week will probably be a 5-6pm close. They're pretty consistent with 5 except Holiday weekends. I could see weekend hours going to 8.
Epcot I could see having a 9-10 close during the week and maybe as late as 11 on weekend.
Magic kingdom will probably be 7-8 during week and between 9-11 on weekend.
