Simon who runs Freeride Morocco is legit, yeah. He's also responsible for Freeride Spain which ran for, what about ten years, but is back in the UK. I've been out to Spain with them numerous times - search for Freeride Spain here and elsewhere and you'll find plenty of reviews - and also out to Morocco a couple of years back.
The Morocco trip was ace, though we were a little unlucky with the weather and got snowed on on the first day. The riding is great, quite loose, steep and technical, a bit like southern Spain, but redder in colour. The trip itself is a point to point thing with back-up. You stay in various gites in the mountains which are pretty basic, but atmospheric and there's a back-up team with a cook and kitchen who sort the food at the stops and meet you for lunch every day.
I'd happily use them again. It's as much a cultural experience - feels quite wild and exotic, reminded me oddly of Nepal - as a riding one. Full suspension's probably not a bad idea. I managed fine most of the time on my Ragley but felt a little beaten up by the end of it compared to the guys on sussers. Some of that, I think, was mental fatigue just from having to pick lines a little more carefully.
I thought it was a good value trip. Great riding. The ground crew were ace, very friendly, helpful and cheerful and Simon who runs the show is entertaining, slightly crazed and good company as well as being a very good rider.
I don't know if that helps, but it might reassure you a little anyway.
