Any hotel on broad st. They get so many clubbers they can't and don't care who goes in and out. Good rates even for a 2nd city.
Malmaison is excellent hotel for outcalls
Malmaison had been keycarded last I heard.
I think it has always has been.However it’s a busy hotel and you can get to the bar from reception so punters visiting a WG or using a room for a WG visit should not stand out. There’s also a Starbucks so it is not impossible to meet someone in the lobby/reception.
