Hi! We are going to experience our first swdas on the March 4 sailing. I have 3 boys - 4.5, 8, and 10. Aside from costumes (if they choose), or maybe just SW tshirts, what should I bring for them? For instance, last time we sailed I brought lots of glow sticks and glow necklaces for pirate night and that saved us from buying overpriced ones on the ship. Are light sabers allowed? How many kids wears costumes? Masks or no masks? Thanks for any advice!
