Other mistake: Having thought that the kids were in trouble, or away when Jason and Maggie go away for the weekend, they call the next door neighbor to check on them and have them call them back at the hotel that they are staying, but they did not give a phone number to be called. A few minutes later, they call the police as there was no answer - and Maggie says "Jason, you didn't even give them a number to call us back" - but they didn't give the number to the neighbor, and the police would more than likely have it for caller ID reasons.
