In reply to mypyrex:
They're fine. Nothing spectacular but perhaps a notch above a Holiday Inn Express or a Premier Inn. The one at Manchester Airport is hideously over-priced for what it is though (compared to other hotels nearby). Other than a fancy blue bridge connecting you to T1, it's very average.
One or two others I've stayed in are decent though. They're not good enough to be snotty about someone turning up in trekking clothes though.
