Travellers to Thailand were yesterday warned to be vigilant in the wake of the military coup, but most local travel agents went ahead with their tours as scheduled. Travel Industry Council executive director Joseph Tung Yao-chung said there were currently dozens of local tour groups in Thailand comprising about 500 tourists, who were safe and whose itineraries had not been affected. Secretary for Security Ambrose Lee Siu-kwong said authorities had not received calls for help from Hong Kong residents in Thailand, but he urged travellers to keep abreast of the latest developments. Hong Thai Travel Services general manager Lau Mei-si insisted travel in Thailand remained absolutely safe. 'We have been monitoring the situation and Bangkok seems to be very safe. There are no troops on the streets except for near the government offices and Royal Palace,' said Ms Lau. 'We do understand the concerns of our customers so we are offering to postpone trips to Thailand by up to a month. We have been contacting our customers asking them whether they want to go or not, but we will not be offering refunds,' she added. Wing On Travel general manager Lanny Leung Kwong-lan said it had cancelled five tours headed for Bangkok yesterday for safety reasons. 'However, we still have 10 groups in Thailand and we have advised them to stay in their hotels,' said Ms Leung. 'We won't be offering any refunds for cancellations but we have given our customers the option of going on another tour,' she added. Peter de Jong, president and CEO of the Bangkok-based Pacific Asia Travel Association, said some bookings from European holidaymakers had been cancelled as a result of the coup. 'Between October and January is when we do most of our business in Thailand. We had the tsunami and we barely got over that, so we really don't need this,' Mr de Jong said. 'So, hopefully this could be over with a whimper in a week and we can get on with business.' Travellers going to Bangkok yesterday said they were not worried. Tourists coming back from Bangkok said the situation was calm.
