Since most people are agreeing that staying at the airport .. I wanted to warn you about the secure US Departure wing.
There is almost NO FOOD available in that wing and what is there is $$$$ and POOR QUALITY. There is one restaurant as you leave the formalities (customs/immigration) and it is normally pretty crowded. I recall it is pickup service and sit at small table rather than a real waitress service.
There is a bar farther down.
There is a take-away cold sandwiches place that is horrible even further down.
The 'good food' is on the other side of a glass wall that you cannot get to because you are in the secured US departures wing. And by good I am only adding a Tim Horton's to a group of poor looking places (can you tell I drewl but have never been over to the other side).
With 2 boys, you will probably need to feed these eating machines .. and what is there will not be very impressive.
Just a warning!
