As above, go online. I've stayed there a few times and I've never seen or heard of WGs touting in the bar. With all the cameras, it's too exposed. It's easier for them to take online bookings and let punters find them than it is to hang about in a bar risking getting spotted and banned from the building permanently.
There are a LOT of girls renting rooms there or meeting punters there, but they try to draw as little attention to themselves as possible.
With Covid now an extra factor, everyone is watching everyone else.
