The situation around Oct 1, the beginning of the MK 50th anniversary celebration, is unique. The nights of Sep 30 through Oct 2 have had extreme demand beyond anything that has ever existed before. Example: for Sep 30 and Oct 1, all BLT rooms, (every size, every view) initially filled exactly 11-months out.
Thus, getting anything for that time period, even for SSR or OKW, may be difficult and will depend on length of the waitlists (probably long) and whether you can find anything by regularly stalking the reservation site.
