I have done it four times now! Mostly to experience Epcot food and wine a few times and once to go to Animal King once. I love how it is Disney on a budget and I can just wander and do a few things then get home the same night! I save on dog boarding and hotel!
I have done several overnights and am now considering an Annual Pass. Spirit often has round trip under 80.00. Crazy and dead for a week after but LOVE it
