Back in the 90’s we started using park hoppers because Magic Kingdom was closing every night at 6 pm in December. MGM Studios was about the same.
Epcot is our favorite park anyway so we’d open one of the other parks and finish every evening at Epcot.
I don’t recall now, parks must have opened at 9 am. We’d close Epcot at 9 pm, and be ready for a new day at rope drop. We’d swim every afternoon and shop in most stores and still have lots of time. We’d eat three table service meals, stay a week at a Deluxe resort and spend way way less than a value and qs now.
Those were the days.
