We actually cruised on the Fantasy one week (I believe) after their last Star Wars day at sea. My boyfriend is such a massive star wars fan, I bought him the Star Wars blanket & Pillow stateroom decoration. I felt a bit like an imposter for not having actually done Star Wars at sea, but always thought that we would just get it next season when they brought it back.
Maybe after the 25th anniversary sailings? They'll need another celebration to spice up the off-season cruises??
