I suggest you read the Sticky: Requirements for visiting Mexico as a tourist ("tourist card", visa etc.) at the head of this page for formalities.
You will be pretty safe around the area - and you will easily be able to arrange trips to Tulúm (nearby) as well as Chichén Itzá (a long day trip), as well as Cobá (not far, and more or an "Indy Jones" experience in terms of being relatively off the tourist path.
You can bet it will be hot, but then again, Florida is at this time of year as well.
