Just found this website, and hoping for some advice. I'm coming over from Ireland and mixing business and pleasure for a three-week road trip in June/July...Orlando, Houston, Memphis, Dayton, Nashville, Charleston, Orlando. Four of us travelling in a hired 8-seat mini-van...two of the others are drivers so we can share. What's the max we could drive in a day...is 600 miles too much? I'm doing this on a modest budget - any particular hotel chains recommended? Should I book accomodation in advance? Any advice would be very much appreciated. Thanks.
