RAPC your report is similar to our experience from 2 weeks ago.
Arrived at 18:30 and was told that our 6th floor room the we selected online for a 15:00 arrival (queen+sofa) wasn't clean yet and the only option was a king room (3 of us!) or 2 doubles on the 1st floor. My wife and I debated the options for a bit and then I went back to the desk where a different member of staff was now present and told me that the room we selected was still being cleaned but the adjacent identical room was available. I don't know if this is a staff training issue or something on the system that doesn't clearly show the available rooms.
By the time all that was sorted it was too late to go out so we had a quick meal in the bar which was pretty awful. The breakfast in the morning was a mess too, all our food was served cold (full English x2 and sausage bap) and they refused to recook it, only offered to warm it in the microwave.
I've stayed many times before where the service standard has been acceptable for the price paid so they are clearly struggling to cope currently. Perhaps scaling back the operation while they iron these issues out would be better than poor service which will disincline future business.
