Thanks for getting a thread going Jon. I'm interested in heading down to Daytona again as well, though it's a bit early for me to commit. Had fun last year though.
Like you, I'll need to get at least a new rear tire on the bike before heading down. I'm kinda waiting to hear the reviews of the new Pilot Road 3, or possibly pick up a PR2 once the price drops after the PR3 is released.
I don't know if I'd want to stay at the Speedway again myself. It was no cheaper than a campground and I was a bit disappointed by how few people were staying there - not much of a social scene once we got back to camp in the evening. I remember checking this place out last year before we decided on staying at the Speedway and it seemed like a pretty decent spot: http://www.daytona200mc.com/index.html
I haven't heard from Tim in a while, so I don't know if he's interested in heading down again or not.
