"Double Cross" is a mess. Eliminate it.
I wouldn't necessarily call it a mess, but I kinda see how it feels like there's an extra step that makes it a little more complex than similar games like Switch or Flip Flop. Doesn't exactly hurt the game IMO, but there might be a tweak that could be made.
To Sam's point, maybe make the starting point the "neutral" value. In the below example, Drew says the Bahamas trip is currently set at $9,760 while ATL is $6,459. Have him preface by saying "Those are not the current values; what you must do is move the slider blah blah blah..." That still gives you a 1-in-3 shot of winning.
