Did you survive the vampire chase at Van Helsing's Factory?
Then be sure to take a photo home from the theme park as proof. Or would you rather have a different souvenir from an exciting and bloodthirsty hunt for vampires and werewolves?
How about a T-shirt or key chain that reveals your heroic deed, but only at second glance: “yrotcaF s’gnisleH nav devivrus I” (I survived Van Helsing’s Factory). Have a look around, but beware: goose bumps are guaranteed!
