I'm missing you by a bit - I'll be passing through on the 23rd (Sat) and 24th (Sun) before leaving Sunday afternoon for Tampa where I have a business conference for 2 days, then driving back through on Tuesday the 26th back home. ; My conference is Mon & Tues, so I decided I might as well head to Orlando after work on that Friday, get Sat & part of Sunday at Disney, and Tampa's just an hour away.
I assume if you're leaving July 20 to drive down, but not staying until July 29, that you are doign a cruise or something first?
Have fun!
