Las Vegas hotel security guards are not police. Therefore, they are not bound by the Fourth Amendment. They do not need search warrants - or a constitutional exception to the search warrant requirement - to search a hotel patron for drugs. However, hotel security rarely searches patrons for drugs without their permission. In practice, hotel security typically sets up checkpoints at the entrance to special events or pool parties. Patrons cannot enter without being searched. And patrons who refuse to be searched can simply leave. And when hotel security suspects a patron has drugs, they typically will call the police.
