If you are planning to rent a car, you can get better rates online.
If you already have an idea about the parks you are planning to visit (X-caret, Xel-ha, etc) you can get better discounts online if you purchase your tickets 7 days in advance.
It is not recommend to exchange money at the airport. The exchange rate at the airport is very low and you will end up with less money than you expect. American dollars are well acceptable pretty much everywhere in Cancun.
