We did the Sommelier wine tasting and it was so worth the extra $10 or whatever it costs. We learned so much (i'm a nerd, i can never get enough learning) and the wines were phenomenal. If I remember correctly there was a Caymus, Banfii, Purple Angel and a few other of my favorites. It's always up to the sommelier but they were fantastic and it was a lot of fun.
We also did a tequilla tasting, well...my husband did, tequilla is not my friend and let me tell you...i had to drag him to dinner, he was literally staggering. They aren't cheap on the pour for these seminars so make sure you don't have any big important plans after a tasting...that's why they do them on sea days! lol.
