Need some advice on how/what to do for a short day at Epcot. Hubby and I are getting off a cruise in feb, getting a rental car and planning on spending the day at Epcot before our 8pm flight. Now the airline has already changed my return flight a couple times and now the latest one is 8pm., wondering if I should just buy the tickets when I get to Epcot that day?, or should I purchase them ahead of time. I just don't want to be stuck with them if the airline changes the flights again. Now we haven't been to Epcot since 2016, and have about 6 hours to enjoy the day there. Any tips?, suggestions?
