Because it is so different from the other resorts. It is a hotel with a zoo attached. If anyone could just drive in & walk around looking at the animals, there wouldn't be any room for the guests staying there! Also, I suspect there might be security problems. When we stayed there, everyone had to sign a release stating that we understood that if we were seen feeding the animals , dropping or throwing anything into the animal area, or entering any restricted area, we would be evicted from the hotel immediately,and liable for any damage to the animals. I can't remember if we would be banned from other hotels, also. There are cameras everywhere, but all of the guests know this and agree to survelience.
