I did flight first this year because I got a grat rate...
$109.00, round trip, ORD-MCO.
But then it was a hassle to get rooms we wanted,
I think booking rooms first ,then watching every day for airfare works better. Because I care more about where we stay at Disney and the price we pay there.
Saving $500 on airfare but then spending $1,000 more to get the resort we want is what happened to me.
