Fly into FLL. Consider Hyatt Place (convention center) right next to the Harbor Shopping area with a Publix market , shops and restaurants a favorite is Duffy's. Quick easy cheap taxi (meter never flat rate) from FLL to the hotel and then taxi or hotel shuttle to PE. I believe hotel is charging $9.00pp to the port. When you return take taxi to get back to FLL.
Try booking Hyatt Place with ValueTrips best rates.
This is really an easy port to sail from and have done this many times. Enjoy !!
