Been travelling to West Palm for over 10 years now for business. Usually stay on Singer Island and work in Palm Beach Gardens. Never pay less than $55 in a Town Car or $45 for a cab at the airport concession. Even pre-arranged cars through other companies, the fare was never less than $50 in a Sedan...
Found E and R Transportation on Craigslist. They charge $2/mile for all local service, well below that of any sedan or taxi in the area. My bill came to $30. Not kidding. Young, english-speaking drivers from NY...very reliable..I will use them from now on whenever I fly into PBI..I suggest you do as well.
E and R Transportation: 561-506-9499.
