We were a group of 5 participants and two guides - and this turned out to be a great size; easy on road logistics/travelling, fun enough for the relaxed evenings. Other participants were a gem - guys this was fun as hell!
The guides were super friendly and really listening to our needs. If -- for a part of the day -- we wanted to have different adventure, we'd split; one guide leading one group and the second guide the other group. Also when on the same road, the group was allowed to split and we could drive according to our wishes (and itches ;-) ).
Stops for food were well planned and quality of the food was great - once you see the variety of the quality Morocco can offer, you begin to appreciate that one tests the restaurants for you beforehand and you get only the 'approved' ones ;)
I especially liked the fact that we ate also on unusual places; e.g. near the lake in the middle of nowhere because our guides knew the old local lady that welcomed us very warmly. And damn good was that chicken tagine.
Riding coastal road, Atlas mountains, Sahara dunes, seeing monkeys, camels, donkeys and all the kids waving at you... makes really memorable experiences.
Bikes were serviced and in good shape.
