Girlfriend knew that I was coming but she slept and did not open the door?

Girlfriend and I went on a short trip. I had work till late afternoon. So I could reach only at midnight. She went early and checked in at 7pm. She knew I was going to reach at midnight. But she slept with her phone switched off and the door closed. The hotel had no one at the desk. So after knocking the door for 10 minutes I had to go find another hotel in the cold, in the middle of the night.

Is this a red flag in your opinion?
