OP, if your plans are at all flexible I recommend you rebook to a location well away from the fire zone. Understand this fire is not even out yet. Rescuers are still pulling bodies from the wreckage.

You're going "later this year" which means within the next 7 weeks. Even if the area is safe and desirable to spend time in by then -- and that's honestly a big IF right now-- rescue, recovery, and rebuilding efforts will extend long past then. There will be enormous demand for hotel rooms for displaced people, rescuers, and repair crews. I'm not saying this to moralize; I'm describing the situation objectively so you can prepare yourself.

A hotel could assert extenuating circumstances or "Acts of God" to void your reservation. Or it could simply walk you. And even if you are an elite member with the Ultimate Reservation Guarantee, how much mitigation is $100 cash-in-hand if it's late at night and the nearest available hotel is 100+ miles away?
