Susan & David

from a Newbie. I didn't realize you were coming down this soon. I sent you a PM with my telephone number.
One of the site hosts gave me the following directions:
When taking I-95 to Jacksonville:
Get on I-295 NORTH of Jacksonville for about 15 minutes.
Go to I-10 West and take it to CR 301. We followed 301 all the way down to 466 and then it is 5 minutes to Belvedere.
Like V07 said, 301 has a lot of speed limit changes and small towns, but we were so excited we totally enjoyed it. ;D
Good luck with your drive.
