Found a few images of San Antonio last weekend from around 1982-1983, scanned them and though i'd share them.
Taken just in front of the Hotel Arenal looking towards Es Paradis and Eden, if you look carefully to the mid-right you can see the dodgems where the sling shot is now.
The next 3 are taken again from the Arenal beach looking towards the mole
