I had booked Tracy Arm first and then decided to add two other excursions, I rebooked all three because that is the way that I understood it needed to be done.( I did put a comment on this last booking that I only wanted 2 Tracy Arm not 4.
On board I only received 2 tickets for each so I don't if it was my comment that generated the correct amount of tickets, or that it just took the last booking. I also received a confirmation for both times that I entered excursions.
