I have heard lots of conflicting opinions about Petra by night. Some say that it is absolutley fabulous, and some say it is rubbish. Could anybody say whether it is worth doing? Is it anything like the sound and light show at Karnak temple in Luxor or the Giza pyramids? I didn't particularly enjoy them, though I enjoyed both sites during the day. If it is like that I will give Petra by night a miss.
