I had a check in yesterday, I had booked two basic rooms and was assigned two club rooms about 4 days out on the app. After I checked in the rooms changed back to the original booked room. Fair enough if the hotel was full etc.. however, I had taken a screenshot of it by chance and on check in I showed the front staff.
They confirmed there were plenty of rooms available and for a 'promotional fee' they could give me two club rooms (again). After a bit of a discussion the best they could do was to give one room the upgrade then for the second room they would only charge one of the two people the lounge fee promotion instead of both. We settled for this as it worked out around £75 total for three nights.
Whilst I don't expect upgrades this experience seems a little disappointing that they would assign these rooms prior to check in then remove them despite plenty of availability.
