We are hoping to book our first Disney fruit but I am confused about the themed day at sea cruise vs an unthemed cruise. For example, if we book a Pixar Theme cruise, will the entire trip be Pixar themed or just that day? My daughters( 5 and 10 at sailing) would MUCH rather interact with princesses than Pixar characters. We will already be in the last group for booking any extras because it is our first cruise; I don't want to further limit those opportunities by booking the wrong cruise.
