While most AP codes are pretty much the same, keep in mind that there are black outs. Usually the week before and after Easter are blacked out and since Easter is March 23 next year you should know that there is a strong possibility that the two weeks surrounding this date could be blacked out. If you know this and prepare for this, then you'll be OK. What this means is to book a resort that you are willing to pay at rack rate and you can afford and if a discount comes out you will save or you could upgrade to a better resort. For example: The current AP discounts is good for checkin no later than March 29th and the next set of AP discounts most likely will start on April 15 (that's just my guess and I could be wrong, but am going by last year when the discount after Easter started the Sunday after Easter Sunday--we shoud know soon). Hope this info helps.
I keep seeing folks post that the AP discount is good to March 30, but the AP website says this:
Rate available most nights for Sunday through Thursday arrivals 2/20/07 - 3/7/07 and 3/13/07 - 3/29/07 at Select Value Resorts. The number of rooms available at this rate is limited. Additional per-adult charges apply if more than two adults per room. Other room types are available at varying rates.
*Savings based on the non-discounted rate for the same room.
Important Details
No group rates or other discounts apply. Advance reservations required. Passholder must present his or her valid adult Pass at check in. Offer will also be made available to certain non-Passholders in other select promotions.
