Our favorite for limo transport to the Port is now Southern Elegance.
Incredibly reliable, spotless limos, book of DVDs to choose from to watch on the way to the Port, soft drinks of your choice on ice, terrific drivers (ours was Fernando), and top-notch customer service (confirmation of bookings, reminders, etc.).
We've used 3 other limo companies in the past with less than stellar results. After a lot of research and reading comments on the board, we tried Southern Elegance last month and could not have been happier! We had a pick up at the Hyatt Airport hotel to PC, pick up at the Port at the end of the cruise to hotel and finally, a pick up at the hotel back to the airport. They handled it flawlessly.....always there on time, helped with the luggage, professional and friendly.....the best!
We also liked that they do not automatically include the tip in the limo charge. They allow you to add your own amount depending on the value of service you feel you received. And they own their own limos.
Never realized that some companies don't and will "farm out" your reservation to independent drivers with cars. We found out about this after a bad experience going to the Panama Canal repo last year....the guy shows up late, then tried to charge us twice, limo was dirty, two bottles of water in melting ice, broken A/C and the gratuity was already added in. Turns out, the company had "farmed out" our ressie to this guy......a nightmare. He even got a speeding ticket on the way to the Port! That was probably a hoot to other travelers that day....a limo pulled over for speeding!
Anyway, Southern Elegance gets our vote and our business from now on!!
