Seville to Algerceris

Try http://www.movelia.es , a clearinghouse schedule site for most intercity bus lines in Spain. They usually only show schedules a couple of weeks out, but it should still give you a good idea. Currently, it shows 4 buses/day Sevilla-Algeciras taking 3.5 hours and costing 18 Euro. However, since the first doesn't arrive in Algeciras until 1 pm, you may find it difficult to get to Fez in a day. In order to have any chance of making it, you'll probably have to aim for Tarifa and take the fast ferry to Tangiers...better schedules and shorter transit time than ferries from Algeciras. Unfortunately, the train isn't an option. From Sevilla, you must backtrack to Cordoba or Bobadilla before catching a train to Algeciras.
