The heater is on a timer, the temperature plummets in winter at night so switch the timer off before you go to bed or the cold could wake you up. Everything else was a pleasant surprise and a novel way to experience the Dead Sea in peace and quiet with an outstanding view.
Wadi Mujib is an amazing place. The only hike open was the Siq when we went, so that was limiting, but that hike itself was amazing. Overpriced though--it cost 21 JD to get into the reserve, and the hike is only about a 2 hour hike. But it was an amazing 2 hours!
We expected more normal hiking trails. The visitor center is actually an adventure center with extreme type hiking. You need to be able to swim, wear a life jacket, not mind walking in deep water at times and not be afraid of heights. There are no flat trails to just enjoy the scenery. There are no restaurants for miles.
