With the guide, it did help to get in easier even though no one can skip the line for security. Without him, I guessed we wouldn’t know how to do and wait for much longer. Our wait in line was about 1 hour 15 minutes on a Sunday weekend National holiday so it expected to be long lines

Historically interesting. Unfortunately, parts of the building are covered after it is used again as a mosque, e.g. the marble floor. We had a really good guide but due to the 1.5 hour wait to get through security, his review became speed talking. However, it is to the guide's credit that we made it through despite the queue.

A great guide, fluent English is understandable even by people who cannot understand it at the highest level. A punctual and detailed guide made sightseeing a pleasure, not a chore. A very small group, but we were lucky, only 2 people signed up for a given date and time, so we were only in 4. Great experience, definitely recommend it!
