Don't know if this will work for you, but it's worth a try. It was way easy for me. I just went to the excursion I wanted. And, even though it was listed as sold out, I check the boxes for my name and my husbands that I wanted the excursion. Then the screen showed that we were waitlisted and Princess would notify us by email if the excursion became available for us. The message also said we would have 24 hours thereafter to book and pay for the excursion. Hope this helps.
