Not crew, but have spent many nights in many hotels around our
various stations.
THE worst, ever has to be Comfort Inn, LHR. Jeez.
The bed covers are about as thin as tracing paper, I've had sheets covered in pubes...Ginger ones as well !
And as for the food, well, I would recomend anyone who wished to lose weight very quickly, to take a few nights down there.
Sofitel in BRU was pretty poor, well, I was appalled at being told the bar was shut, at 2100 on a saturday night, after working a 16 hour shift !
