I suppose it will have an effect on some (and I think Llandudno is over-served by some types of accomodation that perhaps could be lost, mainly larger poor quality hotels which could be converted to housing or other use - the Clarence was a case in point before it closed). However, there are also people who specifically look for good deals in Premier Inns and Travelodges and go to places accordingly. These people might never have come to Llandudno without that kind of offer. There are lots of different types of traveller, some like staying in a cosy b&b, while some could be on business or can't be bothered trawling the net and would rather get a deal with their hotel operator of choice. I think it'll be beneficial for the town.
