However you can easily be moved to another room by the hotel, either by using the Chat function or by calling at the front desk. Personally I would never use the App to select a room I would be unhappy with, that defeats the object of the exercise as far as I am concerned. If I see a room I'm very happy to take then I will book it in OLCI.

Here is a concrete example: Hilton at BOS Airport tends to allocate the top two floors to Diamond members and those who pay for the higher floor or deluxe room options. I dislike the top floor, floor 10, since there are turbines on the roof and I can feel them vibrating on floor 10. Floor 9, on the other hand, no problem at all. So if I see a reasonable floor 9 room at OLCI then I would take it as soon as it shows. If only floor 10 was open, I would simply look again later, or use Chat, or go to the front desk. I wouldn't accept a sub optimal room on floor 10 via the App.
