WDW has extended some hours in October at MK. Has Universal ever done this at their parks? (Non-HHN days @ USF; any day @ IOA)
Well clearly the hours aren't set in stone as they changed for me with less than a month's time before my trip.Nope. Universal's hours are pretty much set in stone. Outside of special events like HHN, I don't think either park is open past 10 at any point during the year, and that's only at the height of summer.
Perhaps they're limited by being much closer to residential areas than WDW? Whatever the reason, you're not going to get extended hours like you do at Disney.
