I took this tour yesterday, and am very glad I did. I opted for both an English speaking driver AND English speaking tour guide. This pushed the price up, but I have found it useful in my solo travel in other places.the guide was great, I enjoyed him, and he was only with me for the first half of the day. It was nice to have a guide inside the monuments to explain everything. Probably not necessary as audio tours are available in multitude of language. I did not regret having a guide though. My able and friendly Driver Ray then drove me to ossia for a camel safari. This was an odd experience. 45 minutes across the arid land (beautiful) to a family compound/village. I was to have lunch there, which I did, after waiting basically alone for nearly an hour sitting under tree. Just odd. Eventually, a really excellent lunch was served in the house, but I was again, alone. I think this would have been ok and fun if I was not travelling alone. It was just, well, a little awkward.
Overall, I really loved the day, enjoyed my driver Ray a great deal, loved the tour, and would recommend again and again!
