Kenneka Jenkins disappeared in September 2017 while attending a party at the Crowne Plaza Hotel.
Surveillance video showed her wandering alone through a kitchen area and toward the freezer.
Her body was found the next day. Relatives and friends questioned whether she was the victim of foul play, but police said her death from hypothermia was an accident.
The lawsuit claims the defendants were negligent because they didn't secure the walk-in freezer or conduct a proper search when Jenkins went missing.
A hotel spokesperson wasn't immediately available to comment Friday.
