Looking for title of horror movie, unknown year.

All I can remember is that it was a horror movie from possibly 80s or 90s,towards the end of the film a group unrelated guests is what I think was a hotel experience either a zombie/undead or demonic occurrence in the hotel. The only part I remember specifically was the end, where it would appear that no one got out alive and soem bystanders outside the building manage to capture footage of the doorway of the hotel shutting with a shadowy figure standing in the doorway.
