Once CP The City leaves in a few weeks, London will not have a single central CP (assuming you ignore Kings Cross which is a useless location) …..
Crowne Plaza Sheffield is an example of what went wrong. This was a Holiday Inn in a terrible state (the room curtains were full of moth holes for example). Instead of booting it out of IHG it seems the owners were promised CP status if they spent a few quid on the bedrooms, leaving the rest untouched. Even now I would say it should be lucky to be a HI but it is actually a CP.
I was at a brand new Courtyard this week and it blew CP Sheffield out of the water …..
