We had our bikes stolen too from outside El Patio. Again they were chained together and the theif was actually seen picking them up together and throwing them into the back of a van!
What we also discovered when we claimed on the insurance is that not only do they need to be securely locked, but locked to "an immovable object". So use the bike racks or window grills if you're in Balneario Plaza (Plaza 525)
