When DD was younger we always did MK first. This year, since we were staying at the Dolphin and arrived late on a Friday--I thought we'd try MGM first. I'd discussed it with the family before we arrived--again the night before--everyone was fine with it. DD loves MGM for the Rock-n-Rollercoaster so I thought this would work out great. Not as busy as the MK on a Saturday, etc.
Well, we took the boat over--rode R-n-R several times, then my big 13 yo turned to me and said, "You know, it won't feel like we're really here till we go to the MK." So, after lunch and a rest, we did just that!
Well, now I know. Next time--even on a Saturday--MK has to be first.
