For those looking for flights to Orlando, Rochester airport (about 35 min from Niagara border crossing) is always cheaper than Buffalo. If you find a great deal at Buffalo, Rochester will be even better. Airtran has direct flights and JetBlue, Airtran, Delta, and US Air has flights to MCO with connections, but are all in the 150 range per person round trip. Also parking is only 4 bucks a day at ROC which is half that at DTW or BUF. ROC also is not very busy, so its better with kids.
