do they allow us to park, use the pool, etc. until check-in time?
Yes you can use the pool or go to the parks or whatever. You will also receive your resort Id's camper/car passes and the complete check in package and a phone number to call later to get your site #
You might get lucky with a site early(we have but not often) but I would not count on it. If you get to the gate at noon and get the same guy we had last year you will not be done checking in until about 2pm. (Slow and clueless CM)
Now I try to not arrive before 1pm just to avoid the frustration of calling back for a site #. I can see the campground is ready. Why are the people that were behind me getting on there sites, I call back and I'm told your site is not ready yet. again, again and again
We spend the night at the Georgia Welcome center. I prefer the Georgia Welcome Area over the Florida one because if we leave the Georgia center at 8 or 8:30am we are at the Fort just after 1pm. perfect timing for us.
The Georgia Welcome center is just over 295 miles or 5 hrs
The Florida Welcome center has free OJ and brochures of everything Florida.
The Florida welcome center is just over 185 miles or 3 hrs to Disney. But this rest area gets me to Disney to early.
Both of these rest areas on I-95 have very large RV parking areas (about 3 to 4 times the size of a standard rest area) I have never had a problem finding a spot late at night.
If you want to run a generator for the A/C-park with the truckers if you want quiet park with the RVers. If it's Hot I run my generator.
See you at the Fort, looks like we are a day behind you.
