Hi and welcome Dan.

I did a trip to the desert in April this year. It was part of a tour we did with a company called Rough tours. We did a camel trek from Merzouga and camped overnight in berber tents at Erg Chebbie. Comfy tents, a delicious meal and music provided by the camel guys.

Then we set off at dawn on camels to watch the sunrise...magical... The desert IMO offers some of the best photo oportunities ever.
If you are interested in the idea of a tour I know roughtours offer all types of itineries and will taylor a trip to your requirements, if you wish to go it alone there are many guides around that will offer the same, but I think it would be wise to check if they have a good knowledge of the area. Best of luck with your trip. Morocco is a beautiful country and I'm sure you will enjoy it.
