I do not think any of the hotel burned at all, including the porte cochre.
According to the two eyewitnesses WATE interviewed in the hotel around 1:00 AM, the closest the fires came were on the OTHER side of the parking lot from the hotel itself. By the time of the interview they said the fires had retreated a bit but were still waiting for the road out to be cleared.

That was a good report. Thanks
The photos I saw were said to be through the automatic doors at the front and said the fire was right there. In the video, there clearly is no fire at the automatic doors and the big fire shown is opposite at the Gatlinburg side, down slope from the hotel.
