Hi MillbrookMom
Be careful with Expedia as I think most of thier policies state that once you book you can't get any money back.
I aggree with the PP's, look at flying out of Buffalo. I assume that you live in Millbrook. We're in Peterborough.

Last June we flew out of Buffalo for the first time with SouthWest. It was great!
It took us about 3.5 to 4 hours to get to Buffalo and we stayed over night at the Sleep Inn ($120 including parking for 2 weeks and a good continental breakfast). Not a big deal really.
We got direct flights from BUF to MCO and at good times too. Departing at 11am and coming back at 12:40pm. I'm still shocked at the flight costs. For my DW, DD5, DS9 and myself it cost us just under $800 total. Yes that's for the 4 of us taxes in, fees in... total. I priced Air Canada and they wanted $2600 for the same thing!!
The Buffalo airport is nice and it's small so it's easy to navigate. I'd highly recommend going through Buffalo.
Check out Southwest for your flight costs at
www.southwest.com and the Buffalo Int'l Airport for more info too
