The one thing that got be thinking hmmm was his Sangri-La experience and how the WG got access to his room. Ditto the NDA punt.
I have stayed in this hotel and as per the thread on his £2.5k punt it is key card access with staff on Ground floor and by the lift. According to OP the WG went up to reception (on the restaurant level) they called him and then they let her up. This is not the type of hotel you would want to do this and your and WG discretion completely goes out the window.
As he is now banned we can’t ask him if his Z lister NDA punt followed a similar process. If that is the case then we know his reviews are indeed fantasy bullshit.
