I rented a car for one day and drove from Cadiz to Gibralter and north along the coast....I can't speak or read Spanish and I had a rough time reading road signs...I suggest you brush up on the different languages you will be running in to so you don't have the problem I had...

I also drove up a one way street the wrong way.....uphill and narrow....I was lucky when a teenager offerred to back my car up to the bottom of the hill......this happened in English speaking Gibralter.....

I used to go to Spain a couple times a month on a courier job....usually there and right back, but this time I took an extra day.....Have fun John
