We live in Western Howard County and travel to Disney at least once a year. We have mixed it up, driving some times and flying mostly with Southwest. I too have been dissappointed in the newer rates at SWA but I guess it is to be expected with the price of gas this high for so long.
But with SWA buying out Airtran I knew it would only be a matter of time that our choices were going to be getting slimmer. They are the only airlines that fly direct to Orlando (which I think is ridiculous in this metropolitan DC area).
We are flying in late January for 84 each way to stay at BCV. When we go on our Fantasy cruise in June we will drive since we don't have to worry about school schedules and can take our time driving. We usually hit Florence, SC or if we can make it to Jacksonville we stay there overnight. Or sometimes we even leave early am around 4am and drive straight to Cape Canaveral. Just depends on what our plans are, work situation, how many drivers and such.
All I know if that if it gets too expensive to fly, I will drive because I need my
DVC fix!
