This was a quick Google search but I remember a few of them having an even cheaper rate for 4+ nights on their site. Busses are still scheduled to run almost hourly by a few companies I looked at. I have almost all of December off from uni so I can get the cheaper midweek rates and I can afford to stay extra days if the TCH or airport in Calgary get shut down. I will look into Quebec City and give it some thought though, it's just the flight is almost $700 from Phoenix.
