I certainly cannot suggest who is best but I do like Uber/Lyft. Last time I was at the airport, Melbourne Express Shuttle had a counter there (makes things easier actually to talk to somebody) and I see their vans a lot in the area. Space Port is another one I see often. Hope this helps!

Yes, All these car rental companies shown on the map offer shuttle services to the cruise terminals. I prefer to drop the family and luggage at the terminal, then go back to return the car and hop on the port shuttle.

Port Canaveral has no less than 6 very good, safe off-port parking lots (with shuttles)! You can hardly go wrong with any of them and will find many positive reviews as well as the occasional complaint! The new kids on the block are portparkingspace and Port Canaveral Parking - both with tarmac spots and shaded options. This map shows portparkingspace is closest and really nice but since Carnival docks on the other side of the Port (5 or 6), GoPort, Port Canaveral Parking and Park 'n Cruise are in the direction of Orlando.

i've been to most (if not all) the airport hotels and don't recall seeing rental car offices! So I bet the answer is no - at least for AVIS, Budget, National, Alamo, Enterprise
