We spent the night at a desert camp run by Berbers and watched the sunset, moonrise and sunrise play across the great dunes. The whole experience was amazing. We drove from Fes to Rissani, changed from our passenger van to 4x4s, and stayed a night at the desert hotel before riding camels into the Sahara the next day after breakfast. I'd recommend staying two nights. One night may seem cheaper, but it won't give you the same experience. If you're coming from Fes by private car, be ready for a 10 hour drive, and longer by bus. From Marrakech, it'll be even longer.
