Beware of Cristal Golf cart rentals, AKA S. P. Golf cart rentals which is written on the carts, along with a phone number that no one answers. (Not to be confused with Crystal in Belize city).
Waited a1/2 hour for a cart with dangerous leaking carburetor, rotten ignition wires that short out in the first puddle, and dead battery so you cannot get going again, once it eventually dries out.
Got stranded 2 miles over the bridge for 2 hours in noon-day sun, missed appointment, no refund, this is not bad customer service, this is no customer service.
