Rent a Car in Cancun
There are lots of places that you can rent a car from when you are visiting Cancun. It is generally advised, however, that you only rent a car in Cancun if you are clued up on their road laws and you feel comfortable driving a car in a foreign country.
You can pick up brochures from your hotel and the airport which suggest which car companies to use, or you may want to book one to be ready for you when you arrive at the airport. One popular company is America Car Rentals, which can offer you a shuttle from the airport and take you to your car, which you can then drive away and get to your hotel.
Make sure that if you are hiring a car, there is somewhere in your hotel complex that you can park it, or if the villa you are staying in has room for it in a garage, depending on the rules outlined with regards to overnight parking.
