We booked a two bedroom for May 1 - 5 and had to waitlist the last night but the waitlist came through a couple of weeks ago. I'd keep checking and also try to see what's available at the Boardwalk. That obviously won't give you access to SAB, but as Bobbi said it's Flower and Garden time at Epcot so the BWV would give you great access to that.
Good luck.
