If money is no object and if you are of a certain age the Princess hotel and transfers worked well for us. We don't use the service often. We used it in Buenos Aires and we were happy with the service.
As others have stated their is a rep. when you get off the plane to meet you .Hotels have been nice. Any yes getting to the ship is slow. If you are one of those that has to be the first on board then the Princess shuttle may not be for you. We have been there, done that so we just go with the flow. We are slow and in no rush.
At the end of the day it is expensive but their is the peace of mind that you will be looked after.
