My wife and I sailed on Enchantment in October 2017 for our honeymoon. We flew from Providence to Fort Lauderdale the day before. At the airport, passing through security, I forgot my money clip in my back pocket and set the metal detector off. I had to be wanded and searched by TSA.
The next day, after arriving at the terminal in Miami, we had to go through metal detectors and I managed to set them off again, despite making sure anything metallic was off.
This continued for the entire voyage. Anytime getting back on board, I would always set off the metal detector. It was a recurring joke between my wife and I and even some of the security staff who recognized me.
Finally our last port of call - Key West - we were coming back on the ship and again, I set the metal detector off. The guard wanded me and did not detect anything. He noticed my sneakers and asked me to take them off and pass through the metal detector. Surprise, it didn't go off. He wanded the toes of the sneakers and it set the wand off, then sent them through the X-ray, which revealed that my sneakers had steel tips in the toes.
