They will show up under Casaway Cay Port Adventures on the day your are able to book excursions (your cruise needs to be paid in full). I just booked one; I was on-line at midnight on the day my booking window opened (90 days prior to sailing fo Silver Castaway Club members)
While I booked it at midnight to make sure I got one, there was still some available the next morning but now they are all booked for our January cruise.
