Bike locks mystery solved

We're settling into a routine - Early morning walk for me among the beautiful surroundings in Shipyard Plantation. Then, after breakfast I drop the family off at the beach (parking is tough) for three or four hours of beach time for them and quiet time for me. Jack and Sam are happy little boys with bikes to ride wherever they wish all by themselves now - no parent to accompany them. This is a first and a joy for them AND the parents. I've rented a bike for myself and will begin training today - probably won't make a long trip, but at least I'll get started. A bit of a difficulty yesterday - boys and Luke rode bikes to the beach and couldn't remember the combination numbers to unlock the lock. So, a phone call fixed that - but the important part was Sam, the 8-year-old finally taught Luke, the 44-year-old how to unlock the lock by pushing one side rather than pulling both! Anyhow, it all came out OK with a plunge in the pool when they finally got back to the villa. It's so refreshing to have fun problems rather than the everyday, run of the mill problems that occur with living life NOT on vacation. I'm LOVING it.
