There is a Travelodge in central Chester I was considering staying at... but then noticed they'd charge around £65 and £115 for Friday and Saturday night respectively, plus I'd need to use a public car park (which, even with the 20% discount offered, would cost a fortune for 36hrs).
Think I'll now be aiming for somewhere on the outskirts, then drive/bus in for the day.
Oh, and for the record...
...except with untidier hair. And a much bigger girth than the last meet. >.<
