for the week in july we are going to disney, airfare has been around $1100-1200 for all 4 of us. I saw today on USA3000 that round trip to tampa/st pete we can go for $738- is this enough of a savings to have to rent a car and drive from st. pete? a car would be about $200 for the week. the flight out of chicago to st pete is only $64 per person, so I was thinking of booking just that leg of it, and trying to get a one way out of orlando with another airline. help!
