Theres a KOA at SR 210 and 95 ( also a TA truck stop there ).There are several campgrounds here in St. Augustine that are easy to access from the interstate but about 15 min away from it.Also a KOA on the beach ( pope road if you look online ) These are at the south end of St. Augustine and near the beach.They will all put you about 1:45 - 2 hours from the fort. If you don't find something and you want PM me and I can give send you some more info ( names, numbers ).favor Dykes is real convienent to I-95 as Donnie said but, I have never stayed there.I don't know what type of place your looking for ( just a place to sleep or beach access etc ).I can think of 7 or 8 right off.Actually, I haven't stayed at any of them here ( gotta camp more than a mile or so from the house ) but, I know people that have.
