I have seen a few people discussing the recent PIN codes that went out in relation to AOA... Strictly for everyone's information, I thought I'd share our experience:
We had already booked Dec. 4-11 at AOA in a Nemo suite. (Thanks to the great info here, I deduced that any possible offer would be cut off on the fourth, so we made arrangements for that date.)
I called to have the PIN code applied and I found out that you can use the code, but you can't be guaranteed a specific suite building... In other words, we used the pin, we will have a suite, but it could be Cars, Lion King or Nemo.
We requested Nemo, as we'd been telling my granddaughter that's where we're staying. It's not really a big deal, but I just thought I'd pass this along to anyone in a similar circumstance.
