Well when I was on my travels and staying in loads of hotels and b&bs, often they'd be with BT. Sometimes they'd just not give me the access key, and quite often that'd actually charge for access to WIFI! Bit BTOpenZone/FON I would often connect for free, hassle free (as the same credentials are stored and used), and I found it really useful. I also used it to connect to my neighbours WIFI when mine was down. So personally, I think it's great. It's one of the few redeeming features of the ludicrous cost.
