Hi - We sailed out of POM last year, and it was a headache figuring out how to arrange the least hassle transport...
There are a lot of shady shuttle companies out there, that have good looking websites, so it's really important to google the company you are considering separately for complaints...
My experience was this: I was on the phone, and almost booked with one company I read a ton of complaints about - like people never getting their money back for a no show pick up... the telltale sign for me was that they said my CC was immediately going to be charged, and while they claimed that they would be able to refund within a certain time period, they admitted when I pressed the guy, that a refund may take up to three months! Luckily I read the bad reviews just in time and kept looking.... SAS, very popular on this board, never got back to me, or answered my questions, and I also did not want to be restricted to their list of hotels....
....so luckily I found QLS Transportation (for Quality Limo Service) - and they were REALLY good and professional. Very responsive by phone AND email, answering all questions, and there was no restrictions as far as hotel for pick up! (we actually stayed quite far north of FLL) Also we could request the type of vehicle, which was a plus, since we had a LOT of luggage. The transport was also private - just our family. But that wasn't all: They explained that my credit card would not be charged until 3 days before the pick up date - and that was exactly what happened. Around that time, they also gave me the CELL PHONE number of their driver for the day of the transfer to the port, which gave us huge peace of mind... the driver showed up on time, and the whole transfer was pleasant, and we arrived very early. I would wholeheartedly recommend them, and actually not even consider any other company in that area.
This is their phone number: 1888 757 0021 . Website:

I found them when I started looking for highly rated transfer services on TripAdvisor.
Now our experience on the way back was the following: We wanted to stay in the Miami area for another day, so we took a taxi from the Disney terminal to one of the hotels directly at the Port of Miami, the Miami Marriott Biscayne Bay, (short taxi ride from hell - driver was awful; took off while I was yelling STOP as I had not buckled in my toddler OR my pregnant self yet, speeding!, and he -almost- took out the Bell Man at our hotel entrance- that poor guy was very upset - I mean he nearly would have killed him. Seriously.)
We then rented a car from Hertz which is directly inside the hotel. And we returned that rental at FLL airport after our stay in Miami.
This option was somewhat low hassle, but not cheap; especially since we found ourselves on one of these toll roads that have no payment option - electronic only - the rental companies know about this, and they have a device in the car - and somehow I found it quite expensive, and that goes on top of your rental price.
Well, I hope this helps someone!
