I booked this motel for the last week of August 2019 in mid-July and received a confirmation about successful booking. Later, I needed to change the dates (making my stay one day shorter) and sent a request which was also sucessfully approved on August 12 and I received another confirmation from Glacier View Inn.
When I arrived on my check-in date, August 27, 2019, I found a note on the motel's door: "Please check-in in the office" with an arrow pointing to the Chinese restaurant next door.
In the restaurant, the owner, a chinese lady, looked at my printed reservation and told me that they couldn't accommodate me because they shut down the motel operation a month ago. She didn't apologize and instead said: "We sent out a cancelation email to all our customers a month ago". That was a lie because I altered my reservation on Aug12 (two weeks before) and they approved it. I did not receive any cancellation email from Glacier View Inn. The lady refused to admit any mistake on her part, didn't apologize, and told me to find another motel in the town - in the middle of the peak season. She didn't even bother to offer any assistance in finding another accommodation.
During the following days, I had been keeping an eye on their motel - it was operational: there were cars at the entrance, big sign on the road, and that door note asking to register at the restaurant.
If you decide to book Glacier View Inn - keep in mind that when you arrive there you may be refused your accommodation for a fake reason.
