FYI, for those who will be going on the weekend following Memorial Day: normally the Friday has the lowest crowds, but this year the slow day may be Sunday because of traffic caused by Gay Week.
The Studios is the "park of the day" on Friday, June 2 for the Gay Week attendees, which will drive up numbers in general, though I don't know how many of them will be seriously into the SWW events. Sat, June 3 is Gay Day at MK, which drives up attendance at the other parks because of severe crowding at MK.
