I would advise travellers to be very clear and specific about dates and length of stay!! I had made an initial enquiry by email via their website to say that I would like to stay one or two nights but not sure of dates. A quick response from them told me I would be welcome at any time. I responded that I would get in touch when I was in Morocco and knew my itinerary.
I asked the Receptionist at my hotel to speak with them and explain that I would be arriving in Meknes on the Wednesday and requested someone to pick me up. On my arrival at Meknes, I was met by a very nice young man (Mohamed) who took me to Moulay Idriss in a grand taxi. He explained to me that the parents and two of the children were not at the house and wouldn't be back until Friday or Saturday!! As the main reason for me going to MI was to "live" with a local family and have some cultural exchange, I have to admit to being greatly disappointed.
However, I stayed for two nights. The hotel was clean and tidy, my room was comfortable, the traditional Moroccan breakfasts (included in the price of 200MAD) were very nice and I enjoyed the 2 main courses I asked to be provided (Vegetable Tajine and Vegetable Couscous). Mohamed introduced me to a young man who agreed to take me and show me around Volubilis - a truly spectacular place to visit.
I'm very sorry that I didn't get to do some local shopping and have cookery lessons!!!!
