We are on the Fantasy August 26 for the DVC members cruise. I got an email from DCL advising that onboard wine tastings etc could be booked in advance online. I went to the site for our cruise and the one I was most interested in, the champagne tasting, shows no availability. Does anyone know if they will take additional reservations once we board the ship, as they do for specialty dining? The champagne tasting is something I would be disappointed to miss.
