Perfect, that is exactly what I wanted to hear and feel assured that this is the right way to go! Thanks for everyone's assistance!
leave as early as you can. 2/3/4am. Taking the inland route isn't bad at all on a Saturday. There is no shore traffic and the camper and weekend people are already where they are going on Friday night.
Like I always say, it's not faster, it's not for everyone, but for the right travelers, it can be smooth sailing. 

then we'll head to south Florida for a week. I haven't decided what we're doing on the way home. We're leaving July 13th so I need to finish planning and start packing!
