If you're talking about the Touring Plans calendar, then they show both. I think they're just leaving the
MNSSHP with * "just in case." The hours Disney gave to TA's and the ones you can find on their site by going the roundabout way (changing the date in the address bar once you've clicked on any date in the calendar, then hit enter) all say the MK is closing at 7 on Friday, not Saturday, which we can assume means MNSSHP is on the 23rd, not 24th.
