Barb and Karla, what website are you looking at booking tickets? Just using expedia, depending on where we fly out of San Antonio would be $265-376 a person and Corpus Christi would be $367-522 a person. Driving for us looks like a 20 hour drive from Map Quest, but I haven't figured it out yet by looking at a map (sometimes Map Quest is not accurate). Lots of decisions to be made, but I would be interested to know what booking sites you guys use?
