1. Have Disney characters walking around the site dressed as alt-rock legends - or vice versa: Kim Deal as Cinderella, Bob Mould as Princess Jasmine, Tanya Donnelly and Kathleen Hersh as Chip 'N' Dale, etc.
2. A Space Mountain-like indoor rollercoaster-cum-ghost train where someone dressed as Steve Albini sits next to you in the car and says a 30 minute tirade of hurtful things to make you feel like a lesser person.
3. An S&M dungeon specifically for Belle and Sebastian fans, where the worst thing that happens is that an Audrey Tautou lookalike hugs you a bit tightly.
