I guess I'll be the lone dissenter because I get so much more done right before closing. I have admittedly only used MM once, but when I did some of the rides were not up and running immediately, and the lines for the rest were fine, but not great. I wished we had slept in. But based on everyone else's experience, I do plan on giving it another try one day. On the other hand, when I stayed late this past December on a weekend, we rode every ride in FL except for PP and all were walk-on or 5 min wait, as were Pirates, BTMRR and other favorites. I would factor in how your group functions in the morning vs. late night. If wait times were the same, would you get more done sleepy in the morning or sore/tired at night? Also, will you have any jet lag? If you're coming from the East, I imagine the early mornings will be easier on you than the late nights.
