There were only eight of us at the tasting. We enjoyed it, but we are not wine connoisseurs and are not picky! 😆 they had five tables set up with a red and white wine from each represented country.
It was mentioned on the latitudes perks pamphlet in the room. I inquired about it at the cruisenext desk on embarkation day and they put us on the list. You have to register with them to attend. Ours was at noon on the first sea day.
You can sign up for a tender time on embarkation day on the touch screens located near elevators or the menu on your room TV. No paper tickets anymore, its just linked to your key card. (At least this is how it was done on the getaway last week.)
