I don't think it will effect our trip this May 15 - 25. We have put the money aside since last May when we were there. We got our tickets very early and got a good deal leaving from JFK, NY (434.00 each round trip) can't beat that one now!
We also have another 2 trips planned this year, one to Grand Canyon and one to Cabo San Lucas, Mexico. We have already paid for air fare and we used time share exchanges for villas. We may cut back on eating out and doing some tours, but that will be about it.
