A mate of mine was recently in the Talardy hotel in St Asaph and overheard a staff meeting in which they discussed Pimps using the annex block rooms (key card access) for bringing young "suspected prostitutes" and they commented that they even thought some may have been underage, and "we dont want that stuff going on here so be aware when checking anyone in and we can inform police" etc etc.
The place only opened the new rooms in an annex in march this year.
