It's kinda' crazy how much the airfares can fluctuate! When we went in December 2006, we paid @ $218/RT (Boston to Orlando) and about 3 days later the same flight was over $500! At one point, it was over $1,000!

It never came down as low as I got it (I think @ $298 was the lowest I saw it).
Glad you got it when you did!
