Stripping out unnecessary words (like character names; no need for them, they just take up precious verbal real estate), the concept seems to be something like this:
A travel agent cons a wealthy actor into staying at his parent's failing resort in the Outback, hoping he will invest in the resort saving his parents from imminent bankruptcy.
Well, I think ?the Outback is a great location for a comedy. ? However, as written, the ?travel agent has no substantial stakes in the outcome, no skin in the game. ? It's his parents' who are?at risk, not himself (directly). ? I suggest the concept be reworked to give him more of a stake in the outcome, more than anyone else. ?He should be the one with the most to lose, financially, emotionally, status, self-worth -- in every way possible.
Maybe he's in financial straits himself because he's mediocre travel agent who can't compete against the Internet which ?has decimated the whole business of personalized travel booking (which it has). ? And then he ?inherits the resort. He desperately grasps it as his only lifeline, his last chance to make something out of his life. ?He doesn't ?just want to ?make save resort for someone else's sake (like his parents) ; he must save it in order to save himself.
fwiw
