I guess by "MA" you mean "Middle East"? Cairo is, on the whole, a much more interesting place to visit than Amman. (There are many threads here comparing them and giving tips.) Also closer to Morocco and probably cheaper to fly to. Both are extremely cheap to visit (hotels, food, taxis, etc), but it's easier to get around speaking English in Jordan. But, especially with a little bit of Arabic, you will have no problem in either. Both give visas on arrival for Americans.

You can also fly non-stop from CMN to Dubai, which is worth a visit and which also doesn't require a visa. August is low season, so prices would be good, although the flight might be expensive.
