US navy crews are some of the biggest-spending visitors to Hong Kong, with a typical fleet injecting more than $30 million into the economy, a survey shows. The Hong Kong Tourism Board released the findings yesterday ahead of the arrival today for a five-day port call of 7,000 crew on board the aircraft carrier USS John C Stennis and its battle support group. The executive director of the tourism board, Clara Chong Ming-wah, said: 'We know they are big spenders, but we wanted to learn more.' For the survey, 300 of the 6,500 crew on board the USS Constellation and its battle support group were interviewed when they visited Hong Kong for a five-day visit in August. It found that over the five days, naval personnel had a per-capita spending of $6,300 - 13 per cent higher than the $5,572 the average visitor from North America spends over the same time in the SAR. The 7,000 crew who start their stay in Hong Kong today will spend a total of about $40 million in shops, restaurants, bars and hotels. The survey found spending on shopping contributed to 61 per cent of total outlay, with 78 per cent of items bought being souvenirs. Other popular items included electrical goods, clothing and jewellery. Ms Chong said 15 per cent of navy personnel chose to stay in hotels while on shore leave and eight per cent were accompanied by friends or relatives. The survey also found that while younger crew spent more on shopping and entertainment, older and more senior members used high-quality hotels, spending an average of $4,017 on accommodation per visit. Ninety-four per cent of the respondents planned to re-visit Hong Kong for a holiday. The survey found the most popular activities were sightseeing, followed by shopping and nightlife. Chinese seafood was most preferred, followed by Western gourmet food. Servicemen and women spent $134 million in Hong Kong last year.
