I see no one has responded so I will even though it was 2013. We did the overnight to Luxor from the Quest and it was a great experience. I would never do the one day. We saw several sights that I can't recall the specifics off hand, but it was a very full two days. Of course, the bus ride is over 3 hours from Safaga. We went to both sides of the river to the major sites. Stayed at the St George which is a very nice hotel. We had to cancel an Istanbul to Singapore cruise that is current on the Regent Explorer and had planned to do the same overnight again. The cost in 2013 was very reasonable. Now, I have no idea. Well, I do have an idea. The Regent cost was $899pp. Your review and photos of the Iceland/Greenland trip in 2017 led me to book that trip so I hope you find this useful.😀
