This is quite a good website for Cancun. http://www.cancunmx.com/


The weather will be goon in Feb. Be aware that the Cancun Hotel Zone has a lagoon side and a Caribbean side. Make sure and look at a larger scale map when seeing where the hotel is located. Not every hotel is on a good beach, or a beach that has water access. Some areas are very rocky.

It really depends on what you want from the area if the Cancun Hotel Zone is the right place. There is also Playa de Carmen down the coast from Cancun, Isla Mujeres and Cozumel, two islands just off the coast to look at.
