Kayleigh Wintercrest is a character in The Sims 2. She is in the game from the end of the introduction and will appear in various places around town. Like many other sims, she can be checked into the hotel as a guest. From her description, she is a scientist who is most likely in Strangetown doing research.

When checked into the hotel, she claims that she is either in town for a conference on the sustainability of nuclear energy or to model clothes for a fashion show.

Her secret is that she only has four toes on her right foot as a result of a karate accident. Concept Art can also be unlocked for her. In addition to being the only character to unlock their own Concept Art by learning their secret, she's also the only hotel guest to have any.
