CHBS Now CHRS!
I must have missed the edition of SROs or whatever medium was used to publicise the switch, but CHBS is now CHRS (R for Reservation). The company providing the service are RHG, they went live today apparently. It takes quite a while to get through to a human operator, but at least they are not in India!
Of course they have no record of who you are, as the CHBS had if you'd used them before, so all personnal details need to be given to them again... If you book UK accomodation, then need to book overseas accomodation they don't seem able to transfer you, so call again and get back in the queue...
