If you book private transfers you have to move your own luggage. One year they picked me up in front of the airport, so I learned my lesson and told the company specifically to pick me up at the hotel. You literally take you and your stuff to the bottom floor on the elevator, walk out and you are in a covered area where they pull up. It was so easy. Then from there they drop you off at the port and the
DCL Porters take your bags. I really appreciated private transfers, no waiting, we were all comfortable and I did not have to worry about my kids upsetting anyone else. Oh and they have always had a car seat upon request. I wish I remembered who we used the second time, they came in an excursion we popped in the movie and enjoyed the ride to the port. But that was two addresses ago (military) and I have no recollection of the company. When we cleared customs I called and they were right there when we came out and straight to the airport to departing. It was so simple and honestly with a party of 7 way cheaper than DCL transfers I think with tip it was like $200 versus almost $500 for DCL. Hope that info helps.
