There are no APs right now, and there is no
DVC AP discount. $6,600 is a lot of money for something that may or may not exist anymore.
Sounds like you could stagger your trips to only need one AP in two years, which would also make it not worth much. I’m not sure why you are buying a blue card at all.
The demand for AKL (and Beach Club!) in lockdown has been staggering. Pre-covid there were tons of listings on multiple brokers, and there were deals to be had if you were watching. I would wait. DVC is not going anywhere, direct or resale. I bet you can pick up a cheaper, loaded contract 6 months down the line.
