mobility transportation directly from ship to port gate

[mystic51]

We are cruising on the Equinox March 14th.  If anyone that cruises before that time and has port calls in Grand Caymon, Aruba and Curacas can tell me if there is any sort of transportation,( golf card, open small bus) that can/does provide a ride directly from the ship to the port gate?  I have checked on the port boards as well as the disability board, and have not found any information.  I just want to get from the ship to port without alot of walking.  Once in port, I will be fine.  I'm having a mobility scooter on board, but don't want to take it with me because it's not possible to take a taxi etc with it.  Any information you can provide me will be greatly appreciated.
