Sorry for the Geography ignorance - On the Freedom of the Seas the stops are St. Thomas, St. Marteen, San Juan. Can you do a tour in St. John's at one of these stops? I was thinking that St. John's was close to one of these islands and you could take a boat or something over to St. Johns when docked at one of these ports. We want to do the Canopy Zipline Tour. Can you do this at any of the ports we are going to be at?!?!? Thanks!
