Can transportation to Cape Liberty Bayonne (RCCL Cruise) be arranged by the hotel and what would be the cost?
I would just call the hotel directly with this question and see what options they suggest.
my experience was that hotel doesn't arrange travel to cruise ship. Try Uber, taxi or shuttle service - depending on the number of persons in your group
The best way we found and cost effective was to use UBER. Down load the app to your phone, pay in advanced. Only possible draw back is you need to meet them on the main street outside of the gate. Always have good service. Fast courteous and when you want to go.
