I have been watching Delta lately for both MCO and MLB and the rates for the cheapest available were 246/pp to MCO and 279/pp to MLB up until last fri when they all went up 10/pp rt. The only thing I worried about and have yet to research, but based on past experiences, I suspect the rental car situation may not be so good with options and prices which would make MCO the best choice for sure. We have driven from WDW to VB and it was not so bad, it is worth the trip unless you have a real early flight out on departure day, that thought does not excite me so we will look for after noon flights. BTW-we can get flights to either MCO and MLB with just one connection in either CVG or BOS which is really good for being at the end of the earth. Good luck!
