My husband and I and our kids (ages 8 & 10) decided to skip the line at the Eiffel by walking to the first and second levels. We had been planning this for months and had a great time. At the second level I stood in line for elevator tickets to the top while my husband walked around with the kids. Out of nowhere a man appeared with four tickets in his hand. He said his wife had gotten sick so he couldn't use the tickets. My first thought was "I must really look stupid today."
The tickets have no date on them. There is only a barcode that is scanned when they are used. Thus there is no hole punch, red mark or any other distinguishing features that indicate the ticket has been used. Even while standing in line I could see a lot discarded tickets on the ground. I hope that nobody fell for this scam. The man disappeared as quickly as he appeared.
