The hotel is still running, staff is minimal I'm sure so they probably are doing buffets to feed the guests they have. The steakhouse where I work in the hotel was shut down for Saturday. We are closed on Sundays and Mondays anyway.
The most miserable fate is to be stuck at work during one of these weather events, and be part of the skeleton crew...the guests' moods quickly turn ugly when they are stranded. I've done it before but never again.
