Any suggestions on whether to rent a car or not? We are going next week and have not decided whether we need a car. We are staying at the Marriott in the Marina and plan to go to \"Downtown\" most wvery night. What about driving to outer areas? I have driven through out Europe but never in Mexico...And if you were to rent a car, what type (I know that my son thinks a Porshe would be good...)????

Thanks. Have gotten a lot of good info from here.
