I agree-the prices seem up much higher than even one year ago! Last year, we did get a 30% off for May/June, but paid much less than we would this year for the same rooms and dates, even if they release a 30% discount. I'm sure they will release a discount at some point, but it might have restrictions and/or the resort you want might be booked by then. I agree with the others on here...the prices at deluxe resorts are getting so high. Looks like we might be exploring a moderate as an option, or a shorter trip, or a California
Disneyland trip instead. $600 a night for a room only is just too much...
Good luck to you. I also think you could consider the Swan and Dolphin resorts, which are walking proximity to Epcot and HS but not Disney deluxe prices. I've never stayed there, but they seem ok.
