We had a nice stay at Beyond Wadi Rum Camp, and met some really lovely people (the experience is what you make it).
Positives: dinner was really nice, guests and staff were super friendly, gas heating in tents was excellent (and necessary in winter!), camp located near little bridge and other walkable sites.
Negatives: bedding appeared to be not clean (and blanket smelled), experiences (4WD, hiking etc) were very expensive, food was sometimes great and sometimes not so great, hot water was a lottery (appeared to work more in the female bathroom and not so much in the male bathroom, and I did not get a hot shower during our two night stay).
