Please correct me if I'm wrong, but I was under the impression that Chacchoben (for example) is an hour from the port ... I can't imagine that long (probably longer) in a golf cart, and I assume that a taxi might get be pricey at that distance. Not to mention ... there is 4 of us, so we'd all have to fit comfortably.
Based on my research it is 45 minutes..... why not just do an excursion from the port and avoid the hassle and worry of getting to Mahahual to pick up vehicle, insurance, refueling, etc.... ? This is just not the port to do this in, but let us know if you accomplish the task and if it was worth it !

People that go to Chacchoben usual just go on a local tour. It's very simple to book it yourself. I've never heard of anyone renting a car to do it, but that doesn't mean it can't be done if you can find someone to rent you a car. Good luck.
Costa Maya is on the mainland of Mexico--not an island as someone erroneously pointed out--you can drive for hours and hours-- however without knowing where your going and how far you want to go to get to the different ruins, etc.I would not risk getting too far off base and miss the ship-- I would take a tour here if you're wanting to get out away from the port and see some Mayan sites. Although they do have a couple of well paved and well marked roads, once you get a couple of miles or so away from the port area you get into some pretty lonely countryside--as I said, unless you know exactly where you're going, the time there and back, etc, I would take a tour rather than a chance.
But, That's up to you. Have a good day whichever you choose.
