Hey Moosebee! I haven't been to Morocco myself, but when I was at the Oasis Hostel in Granada, there were a whole bunch of people who had just been to or where about to go to Morocco, by heading South to Algeciras. B/c Morocco can be tough on your senses, they seemed to use Granada as a docking/resting point before/after their trip to Morocco. I was thinking that if you really want to find out, you may want to shoot an email to Oasis, and inquire them about the whole Tarifa-Algeciras question you have. Good luck!
