I lived in FL from '10 thru '18. I flew my RV to SnF 3 times and drove over another 4 times. I never camped and always returned home the same day. I did hang out in the HBC welcome tent most of the day one visit.
Impressions:
MJ and her crew ran the HBC tent back then and she did a fine job of organizing meals, drinks, cleanup, donations, etc.
The number of actual airplane campers numbered around maybe 20. A far cry from the acres of HBC campers at OSH. Because of the fewer folk camping in HBC, all the infrastructure was scaled way back from that at OSH.
I always arrived early in the day and felt I saw everything there was to see in one day. So I was ready to head home before dark. If I were to fly in from another state, I would consider day trips to other parts of FL while perhaps camping at SnF. The Keys or other towns along the Gulf coast for some of that seafood. I think I miss that the most.
