This looks amazing. We are doing a stay at SSR and we were planning doing the two bedrooms but WOW do the treehouses look tempting after your posts! We are a group of 6 so it would be so lovely and roomy.
Not especially buggy, there were a few outside, none inside the treehouse. One night when I was on the phone for a while sitting on the deck around dusk, I did swat some mosquitoes. There were a lot of lizards, which are harmless and cute. No snakes or gators, though there are warnings to stay on the paths due to possible encounters near the stream.
