Most of the drinks are not regular size.
We did a private Mixology class on the Wonder on Friday... we had a group of 13 and each had four mini drinks, a shot, and a full size drink.
Oh, and I was started off with a shot of tequila since we were celebrating my 50th birthday.
Anyway, the mini drinks were ready and waiting for us, and then we took turns in groups of 3 making full size versions of the minis... and racing to see who could finish theirs first!
I've done Mixology on all 8 of my Disney cruises and wouldn't miss it for anything!
