We are staying at an AI resort, and depending on the room you want the rates I received from my TA are either $727 or $627 for 3 nights, and each additional night is either $229 or $189. We have people flying to Cancun from all over the states (PA, NJ, FL, AL, NY, RI, VT) so I'm not sure what some of our guests paid for airfare. But for my FI and I as well as our parents flights were $538 roundtrip each from Philadelphia to Cancun.
