It's been a few years since I took the tour, but I think the staff largely did just kind of get up and walk away. People stuck around for a few days but slowly stopped showing up as they realized there wasn't any need to hide in the bunker anymore. This allowed the bunker to be preserved largely as it looked while in-use, which was my favorite part to see.
