Holiday Coincidence

Some years ago, we were on holiday with some very good friends in Florida, this in its self was a coincidence as we had not planned the holiday together but found out at dinner one evening that we had booked to go to the same resort and on the same date albeit on different flights and in different hotels! All was going well but we decided we would spend the day apart doing our own thing for a change! Without realising it both families chose to go to Sea World and met each other within the first half hour at the first attraction, we could not believe it. We spent the day together and when we headed back to the immense car park consisting of many different parking zones, found that we were parked in the same zone only a few vehicles away from each other. Neither family knew each others vehicle as they were hire cars and the same make and model and colour as hundreds of other cars hire out to holiday makers.....??????? As we were staying in different hotels in different locations we could not have subconsciously followed each other????? We had not discussed exactly where we would go on the day as there were a lot of options available!
