DLR kind of runs things a bit differently.
Thye have AP rates at odd times and a long way out.
I already booked July with an AP rate.......but am hoping a "code" rate comes out soon to help even more. Those currently are running through the end of March.
As for Easter, I think you need to call and ask the resort. If there are AP rates for that time frame they should already be available (since I have July

).
