It's 4 nights AI (through 12/20/200

Their wedding packages look pretty pricey (minimum $2500!) and so I'm going to get back the exhaustive task of looking to possibly go outside the resort for the nuptuals! Any suggestions would be really helpful!
Oh, and would you believe that the "deal" was through Costco?!! I LOVE Costco!

Before I go booking (and I'm chomping at the bit) if there are any negatives to the resort, please let me know!!!
