As it was first time for the BARDE to collect the figures from website and there were around 70% member hotels finishing their figures submitting before 5:00pm on Monday as required by BARDE, but the rest member hotels had still need my secretary to chase their figures manually as BARDE want to all our member hotels's figures could show on the web page on this FIRST TIME. So BARDE had closed submitting at 11:00am on the Tuesday morning and presented on the website at 13:00; So I have to say sorry to all those hotels which had submitted figures punctually that I had had to break my promise as all those figures suppose to be put on the website in the evening of Monday.
鉴于这是协会第一次在网上收集每周的四位数,大约有70%的会员酒店在星期一下午5:00之前按照协会要求在网上申报了数字;为了保证协会第一次在网上发布数字的全面性,我的秘书又对剩余的未按时在网上申报数字的酒店逐一打电话进行了查询及数字收集,因此协会直到星期二上午11:00才停止了网上报数并于13:00将所有数字在网上发布;所以我本人必须对没有按照最初的承诺于星期一晚间将数字发布于网上而向所有按时在网上申报数字的会员酒店诚挚道歉。
