I will be in Miami next weekend with the wife and kids I am leaving Friday and staying over until Sunday morning.
I have stayed at Bahia Honda a couple of times and it will not disappoint. Its right after the 7 mile bridge (yes its 7 miles long and awesome) and it only about 20-30 minutes from Key West if you want to see the sights there.
If your staying more than a weekend I might shoot down and meet up with you. Possibly Sunday night Monday morning.
Oh, and to answer your question via PM, I make the drive from my house in Florida to Sylva in 10 hours when alone, 9.5 in the 911 once but we will into go into that one.
From my house to Bahia Honda is about 3-4 hours depending on traffic so your looking at 13-15 hours of driving. Your welcome to crash here a night if you need a place to lay your head on the way down. Your more then welcome here anytime.
Drive safe and take it easy in Georgia, they like speeders there.
