I quite agree with you Petra.
As my parents took me for a few winter months in 1964 also, I knew where the best beaches were.
Hence in 1966, when on the exchange visit, I spent practicually every morning on the beach, with 3 German girls, one American and two French boys. So much for learning the language! In the afternoon we did join up with some Spanish teachers at a cafeteria in Alicante.
It was an amazng time, when San Juan, just outside Alicante, was then a wild place, no high rise hotels, just one building with three floors of appartments.
In the Christmas 1964, on our way to collect my brother at Gibralter, we stopped for a while in Albuferra, then a small town. I had one of those Roberts portable radios with me, which I took down to the beach. All of a sudden I was smothered with young kids, from families who were living in caves there. They had never seen a portable radio before so were all very interested.
