Looks like lots of places are now accepting reservations for June 1 so I added that to the first post. My guess is that some of these places are waiting until June 1 to avoid Memorial Day crowds but I do wonder if some might open without any announcement before June 1 to test out their new models of operation.
Weren't these places always accepting reservations for June 1st? Disney was accepting reservations property-wide for June 1st before they pushed that to July 1st a few days ago
