I live in Daytona...the week leading up to Bikeweek can be a blast. The pubs and bars stage parties and such for the locals, these can be a lot of fun. Not near as crowded yet. Also, for those looking to buy shirts and stuff, stick around for the 2-3 days after the event. Everything goes on sale, you can pick up great deals. Like 8 or more event t-shirts for $20.
Also, the motels have deals the week before and the week after. You can get a room on the beach for less than $100 a night....sometimes much less.
Make friends with a local rider, they know all the back ways around town...you can miss most of the heavy traffic. They also know the little known out of the way bars and the great roads leading to them.
