Depends what sort of id though doesn't it? They do not specify photographic id or official, just suitable which is totally open to interpretation and could mean a Boots reward points card.
Also the rooms are listed as single gender or mixed gender.
There is no mention of single sex rooms that I can see.
There is nothing stating that women are protected by single sex dorms and everything to suggest that gender is the qualifier, which as we know means fuck all.
What was that advice on the guide thread, sturdy pjs?
