HILTON Hotels Corp is planning to develop a string of hotels across the region, building on the model set by the Conrad Hotel in Hong Kong. Hilton Hotels president (hotels division) Carl Mottek said: ''We think the growth opportunities for this industry are much greater in Asia than anywhere else on the globe, and we are going to be shopping around for opportunities quite aggressively over the coming years.'' The group, of which Conrad Hotels is a subsidiary, is already at work on hotels in Jakarta, Surabaya and Kuala Lumpur, all due for completion in 1997. Next on the list are China and Vietnam, as well as the more developed markets including Singapore. US-based Mr Mottek said: ''Today's under-supply is usually tomorrow's over-supply and this is what happened in many Asian cities going through the cycle - Jakarta, Singapore and Bangkok. ''But we believe we need Conrad representation in the major markets of Asia, and with our experience we can make these profitable for the owners and our company.'' The first wave of new hotels will be focused on the capitals and major cities of earmarked countries. ''We are very anxious to develop something in Singapore and Bangkok, and hopefully in Vietnam when that opens up. We are also thinking of India and, of course, China and Korea,'' Mr Mottek said. ''We will look at capital cities first or maybe second, and certainly Shanghai is one place where we would like to be represented. ''But wherever we go, it has to be economically viable. We would never build just for the sake of having a hotel. It has to be a good viable investment and there has to be a need for the hotel, and it has to be conservatively financed and must be of a quality to effectively compete with existing facilities.'' The Conrad Hotel in Hong Kong, where the doors have been open for just over three years, was establishing a strong reputation, he said. Both this month and next - traditionally a robust period for both business travel and tourism - will see fully booked rooms. Average occupancy over the year is around 70 per cent. Mr Mottek said: ''The Conrad Hong Kong has done very well this year. We have had a great year in terms of occupancy and total revenue, and are expecting an even better year in 1994. ''It will be the base for further expansion in Asia and sets a prototype for the new hotels.'' He added that Hong Kong itself was doing well as a destination, being at the crossroads for business in Asia. and a centre in itself for business and supporting activities.
