If you are planning on seeing a lot of Morocco (and there is a lot to see), then you can always enter and exit via different ports (as I mentioned above) and see the country in a sort of U shape?
Tanger is the most popular port (on the far north west side), but Nador (north east) is equally accessible from Spain, although the ferry takes a lot longer - at least that way you wouldn't be covering the same ground?
