I don't know if I'd call a lot of the things described in this article camping. If I paid $200 a night to stay in a cabana in the Caribbean, eat three meals a day and have access to a bar, I'd say that I spent my vacation at a Caribbean resort and wouldn't dare to call it camping. Likewise, I don't think it counts as camping if you do the same thing in a forest in North America. I think it would be more accurate to call these places "Outdoor resorts" or something similar.
I don't think you have to hike 20 miles into the forest to camp, but I think the level of service and amenities provided at some of these places shift it away from being camping.
