No proper Star Wars party should be without a Star Wars Cantina or Chalmun’s Cantina, as it is actually called. Cos-play can be serious work, and lots of costumes are really warm (just ask my daughter after wearing her Chewie costume for 4 hours). So you need to make sure your guests are well hydrated. Just promise that all lightsabers are checked at the entrance – we suspect all your guests will want to leave with all their limbs intact.
