Down here along the coast they call it the GOLD coast for a reason!
I would recommend looking at the state parks toward the center of the state. The coast is built-up out the ying-yang with the traffic and all that goes with it. There are a couple of wildlife areas not too far away with VERY primitive camping, but anything commercial is high priced and packed that time of year. And the roads and traffic are nothing close to enjoyable riding.
Guys I know here trailer to Daytona, unload in the hotel parking lot, ride for 4-5 hours, for a total of 6-8 miles, load back up, and get drunk and pregnant dog about the traffic! Daytona Bike Week is all about the social experience and partying. The riding is not much to get excited about, unless you like duckwalking in stop and sit traffic. You need to get about 10 miles away from the strip before you can really move. And I doubt the road work on the I-95 - I-4 interchange will be done this year. It's been on-going for about 2 years. Ed L lives just south of there and could give you some tips about Daytona from a local's point of view.
The center of the state is not built up as much and the county roads are better to ride than the packed state highways. But Fla. has a LOT of flat mostly straight roads. Don't bring the Cafe bike, you will just get board and a sore butt. Ride something comfy you can sit on most of the day and look at the orange groves, cows, phosphate mines, and woods. And CRITTERS! We have all kinds of roadkill here, opossums to  hogs to cows! Not all bad, I have seen at least 5 eagles in the last month. (live, not roadkill) 4 black wild hogs on the roadside watched me go by yesterday. Night riding in rural areas here can be,,,,,,exciting! A real good headlight is recommended.
Fla. in the winter and early spring is great for getting out of the snow, but we have no Dragon Tail, or challenging curvy roads. But stay away from the tourist traps and enjoy the easy cruising and warm weather.

pregnant dog,,, I love the filters!

DuPuis is about 35-40 miles from me, I have been there several times, bike riding and photography. The Family tent camping are spots with a fire ring and hopefully the grass tamped down. I'll check out the equestrian area next time I'm near there. NO WATER take EVERYTHING you think you will need, including BUG SPRAY! Nearest store or restaurants are in Indiantown, 10 miles away. Take a tent with a closed bottom, they have plenty of --

As Charlie Daniels would say.

$90.oo for the entire 10 days ?  I could do that !  even if we don't stay the entire 10 days .  
I could bring a camp stove (one eye) and associated gear.

??????

I don't think we should wait very long to lock it in ...

I went in 2014 and spent a whole day at the big Harley shop and the surrounding venders.   Spent the next day at the Racetrack .  

Stayed at the Abate campground at the Fairgrounds just south of Daytona.

If there had been a group of Savages to ride with then I would have stayed longer ... The road quality in Floeida is not like NC. so I came back home .  
I enjoyed the day at the Harley shop and the (was it JB Cycles) surrounding area the best.    The visiting at the campground in the evenings was good too  .

Only a short 18 miles from Daytona !  

If , there is very much intrest I could ask for two adjoining camp-sites .   My tent is a 8x10 ... sleeps two nicely ... w/cots/gear under cot.
claimed to be a 6-man tent , so there is floor space left over.

I'm with you Buddy !

Figure it out and we'll either run down the parkway and stay at the bottom of it ... or ... run down through Ga. and hunt a place to stay when we get tired of ridding for the day.
I can be gone for a week or two , for two or three times durning the year without being in too much truble when I get back home.        
Makes me think of those two fellers we met at Dragon Central a few years back ... they were both (late 50'ish-early 60's) ridding Harley's .   They joined us at the fire pit one evening .  Just Motorcycle Touring and enjoying the ride !  

I've got 5 or 6 of those military style cots , your welcome to borrow one of em.  They fold up like a bag chair and are good  as a camp-chair too.

Hi guys, just picked up on this thread and will get some ideas together.

Hay , I'm in that Flock !  

By Spring (March) I'll be ready to "Take-a-Ride" !   Far as Daytona goes , I'd like to check it out for a day or two, but there is a lot of Florida to go see.   Just ridding along the beach Hwy. comes to mind .  

Or

Through the Swampy area to see a Dinosaur ...  

Long as no gaters  come to dinner , all is OK !

Just bought some cold weather mitts .

Thanks for the idea fellers !    

yea , I got the brush/wind guards , ordered them first before I found out about the mitts to cover them .   Why didn't I know about this sooner.
