More Cheung Chau guesthouse operators are offering rooms at cheap rates by the hour to youngsters, islanders say. Controlled by the Hotel and Guesthouse Ordinance, the flats are not a high priority for licensing and inspection staff who are kept busy policing budget hostels. Some residents have called for the immediate shutdown of the guesthouses should they be found to be involved in underage sex. Islander Choi Fung-lai, 53, said: 'They only want a place to do the dirty act quickly and so they don't bother to rent a flat overnight.' Cheung Chau Holiday Flats' Association chairman Eddie To Kwong-biu said he was aware some flats were rented as 'seedy love hotels' to youngsters. But he had not heard any complaints.
