Honestly, I always hated the effort it took to leave MK. You've been there all day in the heat and crowds and you're tired and you just want to go home. So then it's another hour or more shuffling in crowds and slow moving transport trying to get across the lake, then more crowds trying to get a tram, and (for me) then you still have another 90 minute drive back home to Tampa. It would always be such a long process and definitely a lot less magical then arriving.
* we were FL AP for a decade or so pre-pandemic but haven't been back in several years so this was my experience
