I agree with Jersey shark.
DH has been travelling to Toronto weekly for the past two months. He usually uses AirTran to Buffalo because it is so convenient. He leaves the company car offsite at Sunpark.
If you can't stay overnight at BUF and get free parking with the hotel, Sunpark have coupons on their website.

Anyway, last week his plans changed so he flew home for the weekend using AC on a special weekend rate. He was near the airport and the thought of driving to Buffalo didn't appeal to him! After he got over the SHOCK of the amount of taxes he had to pay on the $184. special (so soon we forget.......) he thought at least he was closer to Pearson (hotel was in Oakville)
Friday morning he hit the 401, fought traffic, lined up to check in (he usually preselects his seats and prints his boarding passes ahead of time with AirTran) lined up for customs, hurried to the gate (for those of you who have heard the term, T2 Siberia - that was where his gate was - pretty close to Mississauga City Hall) He was now really close to departure time, really frazzled, only to find out his flight was delayed by 1 hour
He could have driven to Buffalo in the time it took to go through all that hassle.......come to think of it he probably could have driven home to Atlanta!!
All he said, in a very dazed stare, was "Never again!"
The moral of the story - an extra hour and a half on the QEW is sometimes worth it.........think of how relaxed you'll be when you arrive at WDW (and the money you'll save on the fares and taxes!)
Whatever you decide - Have a great trip.
