My TA is looking into the Comfort Suites. I think she said I could have a Suite (there are 6 of us) and shuttle to the airport for $90 US. I did not think that was too bad.
Also, I think from Kitchener you are looking at 2 hours. My DB and DSIL fly out of Buffalo often from Waterloo and say that is how long it takes. We are from the Goderich area (lake Huron) and we are counting on 3-3.5 hours.
