Taking into consideration the rising operational costs, compounded by the required low visitors-to-guide ratios, an increase in ticket prices is planned for each year of the biennium 2004-2005 for all categories of visitors taking the guided tour at Headquarters.
鉴于业务费用增加，而且游客与导游的比例下降，因此计划在2004-2005两年期内每年提高总部各类有导游陪伴的游客的参观票价。
