I just found out that the cruise we booked for next year is a Star Wars Day cruise. What does this mean? How will the cruise be different and do I have to pack/prepare anything special for it? We are first timers, so I really don’t know what to expect.
I’d suggest looking at these posts: http://disneycruiselineblog.com/?s=star+wars&submit=Search
The ones with Navigators will show what kind of schedule there is each day.
