This is a true gem in South Florida, a remote island paradise. Miles of beaches with very few people and great hiking/biking trails through the scrub. Pack lightly as you will need to load and unload all of your stuff on the ferry and then the tram and then carry it to the campsite. There is no electricity but cell service with AT&T was great (not that I wanted to use it much). The camp store sells souvenirs and necessities (snacks, cold drinks, firewood, ice, more insect repellant). Restrooms are clean and there is potable water available there, so no need to bring your own and waste plastic. I was glad I didn’t bring my kayak, as it would have been a lot to haul with me, and I rented one for $20 for a half day on the island. Although bikes are also available for rent, I would probably bring my own bike next time as it would be helpful to get around during the 4 days I was there and find more remote locations.

Insects are a serious issue, even in the fall and winter. Hope for a breeze to deter the no-see-ums. I used DEET spray and a thermacell and a permethrin-treated tent and still left with dozens of bites, and that was in November. Next time I would wear pants and long-sleeve shirts in the evenings. Fortunately I didn’t see any rats while I was there  

My campsite was #13 and it was one of the smaller ones but well-shaded and apart from the louder cabins. Some campsites have hammock posts and otherwise you are not allowed to hang hammocks on the trees, so plan accordingly.
