Count me as one of the ones who does not rent a car. The first trip we did, we drove it from the airport to the CBR and from the CBR to the airport, huge waste of money. It isn't a vacation for my husband if he is having to drive around and figure out where to park, then find the car when we are done etc. Plus we stayed at the Poly last trip and used the monorail and the boats so much. We didn't have any trouble with the buses at all.
