We've signed up for the Absinthe and De Profundis add-on, and the Agua Azul (I Can't Believe It's Not Tequila!) add-on.
We also have reservations for the 1:30pm Eau de Vie seminar. This is very limited attendance, only 15 people per session and only 2 sessions. I would suggest calling in now and making your reservation when you buy your tickets.
