Most car rental companies will ask you for Mex. Ins. to be bought thru them at the end you are looking at somewhere in the $100 per day and if you rent a larger car even more, the easiest way will be to get your round trip fare for $125 from us and we'll pick you up at your house, hotel or airport (sorry!! Tucson only unless you have a group of 7 or more) and take you to the door of the place you are staying in RP, once there you can rent a car from Mar de Cortez Rental Car phone 102-0990 or cel 638-113-0022, all you need is a driver license and a major credit card or use the local taxis for about $2 per person, I would not pay more then $6 if enough people to fill the taxi the other Taxi "Turistico" will be a lot more expensive
