Well, on Disney Channel it ended that the dad's partner took the money, and they figured that out. Potentially everything was ok, but they were broke because of the money taken away and they couldn't find the person who did it.
During the alternate ending it was basically the same until the last 2 minutes. Instead of him never being found, Courtney found her way into the compter system (or something like that) and found out where he was running away to. They looked up the hotel and they had a live video of the lobby, and he was on it. So they found him and everything was gonna be ok.
I don't know how much of the movie you saw but I wrote a long recap so you can read that for more info
Hope that helps!
