That Hostel looks way too swanky for our tastes. :-D We generally camp it, though my wife and I just sleep in our car rather than a tent. The last two years we have gotten to stay at a scout camp in the everglades park itself. Extremely nice location with fantastic facilities including a commercial grade kitchen where we did seafood night this year. It is even a stone's throw from where we found the diamondback. The down-side is that it isn't actually open to the public. Which is, from our standpoint, an up side.
When my wife and I travel alone we tend more towards sleeping in the car at rest stops etc. or at tenting campsites. That may change as we get older .. but for the moment the front seats fold to meet the back seats and once you get the hang of it it is pretty comfy.
