Hi Graham
Have also recently done this tour.
The sites were really quite amazing and not to be missed.
I was also concerned about meal arrangements when they were not included, but for us it was really only one night.
The day we arrived was so late that you had to be content with the in flight meal, maybe put some provisions in your luggage. The next evening there were several restaurant options in the hotel, and we shook out into different groups depending on your food preference, After that all meals were included, but do not expect a wonderful culimary experience. Also if you like wine, it had to be bought by the bottle, so you need a friend, or a pen to write your cabin number on the cork, if you are not up to a full bottle at one sitting.
The loacl guide was very knowledgable and very helpful. The days were long. The weather good, exhaustion only set in after I got home.
Hope you enjoy.
