Thank you. I also saw that the Rhapsody of the Seas (1,996 max passengers) and the Viking Neptune (930 max passengers) will there as well.
I am confident that we can be on an early tender leaving our ship. My research also shows that passengers on any ship organized excursions will tender to a different port at Santorini, allowing the rest of us to go to the "Old Port". This SHOULD help, if correct....as many people buy the ships excursions. (they were all sold out for Santorini when we booked the cruise....we generally shop around as well)
However, these ship purchased excursions may leave passengers at the top after the excursion, requiring them to use the cable cars to return to the tenders at the Old Port.
Regarding paying for the cable cars with a credit card, I have seen both yes and no, so I am hoping for a recent experience to confirm. (Perhaps this ability has changed?) I plan to buy Euros at a bank ATM in Fira, and will then have Euros for the return cable car tickets.
Thank you again for all answers!
