We were on the Dream 6/13-16. Were disappointed that those classes were only offered while we were in port at CC and Nassau, with the exception of whiskey and cognac tasting (9pm). For example, Mixology was 3pm on Thurs (Nassau), Margarita @ 3:30, Martini and Wine both @ 4pm. You'd have to cut your port time short in order to attend these. I figure we'll need to do a 5-7 day cruise where we have sea days in order to get to one of those classes/tastings.
