Don't worry if you don't have time to learn about it all. We'll be going on our 3rd Stars Wars cruise next month. I've only seen the first 3 movies(that came out when I was a kid, 40 yrs ago) and my dd hasn't seen any. She was 8 yrs old and 10 yrs old on our cruises and 11 yrs old for our upcoming one. We aren't SW fans, but like to cruise in Jan, on the Fantasy which is always SWDAS. We didn't know who any of the characters were, but still had fun doing the different activities. I don't know anything about Marvel either, but it looks like it would be fun. Have you looked at any past trip reports on here? That could give you an idea about which characters they have on the ship.
