Inspired by classic Let's Make A Deal eps. that often involved contestants guessing amounts of foreign currency, I've decided to try and apply the concept to TPiR. The game would also be unique in that it would be the first-ever dedicated trip game on the show.
The contestant would be shown three trips, along with an amount in each destination's respective home currency (obviously, only trips outside the US would be used). For each trip, the contestant would first try to guess how much the amount shown is in US dollars, as determined by the exchange rate at the close of the markets on day of taping. If their guess is within $1000 of the correct amount, they now play for the trip plus a $2000 "spending money" bonus; if it is not, they play for the trip only. Then, the contestant would guess whether the amount (in USD) shown is in fact the ARP of the trip or not (a la the "true or false" portion of Five Price Tags). If they are correct, they win the trip plus the cash bonus, if applicable.
This process is then repeated for the next two trips, with the cash bonuses increased to $3000 and $5000, respectively. If a contestant guesses the true/false portion incorrectly on any trip, the game ends, but they still win any trips/cash they accumulated previously.
