Our first trip to HHI was in 2011 and we arrived on Easter Sunday. We booked at 7-months and got 5 nights in a 1BR without a waitlist. I will point out that this was before online booking so I think that may have had something to do with our luck. We bought a HHI contract in Feb 2011 so that we can go for 5 nights over Spring Break every three years without stressing at the 7-month window.
