I know that makes it obvious for a premium price add-on and clearly hotel owners in the UK and Europe can't resist the temptation to charge you a ridiculous premium to hook up to their networks.

I really do wish, however, they would see the sense in the American model. When we drive along the freeways into any town we look for the "Free Internet" billboards and - all other things being equal - we will check out the hotels that offer free internet.
In other words, American hotels seem to see the internet as a 'deal clincher' - something to entice people to their particular hotel - not something to rip off the customer for more money.
Come on hoteliers! It can't possibly cost you that much to allow people to access a WiFi network. So why no use it as a promotion to get people into your hotel, rather than the one down the road?
