I often receive email specials. You can watch up to days before you leave for specials too. On a Sunday last year ds said he was going by train to Disney, taking the auto. I went online and found an $80 flight for Wed. and met them there on Thursday to granny sit.
we drove back. But, i and dd get anxiety/panic, she gets car sick. I have a lot of arthritis in the lumbar and back. Had I known, I would have booked flights back.
If a last resort, would drive, but with last minute seats to be filled maybe you can find something.
The other thing too, lf you do not have a travel friendly family, lots of stops are needed, stressed drivers, whiney kids, days lost on endless miles, it is not good times.
Sign up for Orbitz, hotwire and watch the fares.
But, if you find a great fare, and then go back later, it will be higher....It is a way to hook in on some sites.
I also agree to watch for alternate airport. To get on a nonstop flight for just over 2 hours as opposed to 2 days each way on the road is not worth it if flights are found for $900. Between raising gas cost, tolls, food on the road and motel....
You could save money staying a day earlier or later to work out flights at another hotel.
However you get there, enjoy.
