Hi folks,
We're working on a revision to the calendar, probably out sometime this weekend. We've not yet finalized the crowd levels for each day, but based on the increase in crowds we've seen this year, I wouldn't be surprised if some 2s turned to 3s or 4s. The first week of December looks to be getting a boost, as does October, IIRC.
The new revision will also include a description of just how much the day of the week impacts how long you'll wait. The worst-case scenario for the Magic Kingdom appears to be on Sunday, where crowds add about 20 minutes of extra waiting in line when doing a comprehensive touring plan. (The best day is still Tuesday, obviously at 0 incremental minutes - every other day adds between 1 and 19 minutes to your overall wait time, assuming a good touring plan.) How do we know this? We had people record wait times and ride rides for approximately 3 weeks so far this year, in the MK alone.
Hope this helps!
Len
