I appreciate all the responses. I've gold status with Marriott, which I place little value on. But when I talked with Marriott corporate, I put my MR number in so presumably they were aware.

I've stayed at this property before and the FD clerk told me that they have less than 80 rooms, and because many will choose that property when their home is being remodeled or whatever (it is a Residence Inn, they have kitchenettes), even driving 50 miles or more in order to do that, they have less capacity than one might expect based on appearances. A good number of the rooms are also used by guests who come in to work in the area. When I was there before (spring of 2018), even though I was by myself, they put me in a two-bedroom suite, presumably because that was open for a points stay. All the one-bedroom rooms were apparently sold out. I've stayed in the neighboring property last April, for the Chico Wildflower (cycling event), and everything was sold out for that event. I figure how much more for a fire that burned down the homes of more than 25,000 people?

Right now they are showing as sold out for our dates, so I'm playing it by ear. I'll ring them before heading up to be sure we actually have rooms. Fingers crossed. As one respondent noted, it is costly to stay in a hotel for 7+ weeks, and I'm not sure how many people have insurance coverage that would provide for a lengthy stay.
