Disney offers mixology classes that anyone can sign up for once you board the ship. However, you can request your own private mixology class too! You just need someone to take the lead and be the organizer. There's a form you can fill out and send to DCL. You just need people's names and stateroom numbers. Their rooms are charged so you don't have collect money. DCL will determine the day and time and then you just show up! I did this on the Dream in November and it was SO fun! We learned some history about rum and how to make our drinks. There were 4-5 drinks in all. Best $18 I ever spent! (And maybe we got the bartender to give us the extras that people didn't want. Haha!) Can't wait to do it again next year!
