I have paid my cruise in full and I'm within my activity booking window. I booked a cabana online yesterday and it does show up in my reservations section. However, when I go to the page to add another activity, the cabana I chose still shows up as available. So, is it technically available for someone else until I pay for it? Or is the site just slow in updating availability? Speaking of paying, I didn't think payment in full for the cabana was due until much closer to the sail date - can anyone confirm when I need to plan on paying it? Thanks so much!
