When Saja Rafaeil first noticed shadows inside a bathroom stall on MSC Cruises' Meraviglia ship, she didn't think anything of it. She and her husband were on a sailing that visited Mexico and the Bahamas when she got up use the restroom one night as they were relaxing in a lounge onboard. "I tried to ignore (the shadows)," she said. Then she saw a hand holding a cellphone reach underneath and upward. "And then that's when I freaked out a little bit." Saja, who asked to be identified only by her first and middle names because of the nature of the incident, alerted a crew member outside the bathroom who came inside and knocked on the stall door, along with another passenger she had met onboard. Saja also began filming on her phone so she'd have evidence, and she posted the video on TikTok. When the door opened, a male crew member walked out. Saja is among a number of travelers who say they have been filmed or spied on while traveling, whether by a covert culprit or via a hidden camera in their accommodations.
