Note that you are likely to need a reservation for the free wine tasting event. On my last cruise, I tried to reserve a couple of days in advance and was put on a waitlist, which I eventually cleared. Our tasting was done in the front half of Blu dining room, so capacity was limited. In times past, the event was held in a section of the main dining room and had a larger capacity. On our 14-day cruise, there were two free wine tasting events.
