I don't know to be honest. If it were other regions closer to home I might have an answer for you. But truthfully $109 doesn't sound too bad. We are planning to be in that area for a week long pre cruise stay, but intend to rent a car while we're there. For that we will need an International Drivers License.
I have heard the trains are pretty easy to use. You know I would ask this question on the chit chat board, becaue there are several folks there who have cruised in that region and are very knowledgeable. I will be interested in their answer as well.
