I believe there is a cut off point where you can no longer make changes to your excursions, spa and Palo ressies online, does anyone know what the cut off is? We are sailing 1 week from today and am on the fence about one excursion we booked. I thought I had read somewhere it was 3 days before sailing, but of course now that I need that info, I can't find it! Anyone know for sure? Thanks!
