In December 2014, I took a ferry from Spain to Tanger and, a few days later, crossed into Ceuta, after which, again a few days later, I crossed back into Morocco.
Getting into Morocco, from Spain, was a breeze. Immigration was done on the ferry.
Getting into Ceuta was a bit more cumbersome, but not a huge hassle. I waited in line for perhaps 20 minutes. Getting back from Ceuta into Morocco was easy as well.
On the whole, all crossings were fairly straightforward, and I never felt even remotely unsafe.
I traveled on a Dutch passport.
