We are going to be in Orlando Oct.14-21 and while the majority of our trip will be in WDW we wanted to visit Universal/Islands of Adventure one of the days. My question is when Halloween Horror Nights is taking place do both parks close down or does it only take place in Universal? For example if we went on a halloween Horror Nights day would Universal close early and would we be able to still go to Islands of Adventure and enjoy our time there without any of the horror nights stuff?
