Lol! I, too would have loved a camel ride and overnight in a Bedouin tent in the Sahara, but the length of the trip there and back put me off. However, since you've got a whole two weeks, why not enquire with your hotel (might be cheaper than first choice?), and go in a jeep, do the whole thing and ride your camel? Depends how deep your dream goes, I guess!
On another note, if you can do an overnighter to Essaouira (you could do a day-trip either), you might find it a welcome, breezy and relaxing alternative to Marrakech. It has a lovely long sandy beach and a really chilled-out feel, with some great sunsets over the ramparts. It's about a three hour drive I would say (maybe a little less), or a cheap bus trip there and back. Whatever you do, enjoy
