Wow, I just found this thread, what an awesome trip!
In 2021 my wife and I went to some of the same places in Morocco. We were thinking the vaccine was out and everything was going back to normal... Then were in country as the Delta variant took off in Europe and moved to Morocco.
One one hand it was incredible as we literally had the place to ourselves in a lot of spots that would normally be busy. Amazing restaurants, riads, and the tours we did... often we were the only people there it was like a private experience. There were so many people in the tourism industry who had been locked down without much income for almost a year and a half who were so grateful at having business starting back up, it was often really moving (sadly a false dawn.) We had a few days before and after, but from Fez, over the mountains to the desert, back over and ending in Marrakesh we had a Berber guide for a few days who drove a Prado. He was a big help with all the checkpoints.
It is one place we both agree we want to go back to, but we definitely need to work on our French first!
