The dates for their trip arrangement is now March.17th to March.23rd.The reservation for this hotel has been settled（不清楚这里“非常好”有没有更具体的意思,因为英语是一个十分精确的语言,这里暂时翻译为“这个酒店的预订单已经确定下来了,如有其他意思请告诉我）,I will contact you,if the schedule has any alternations.Thank you!
But for it to match the time on the invitation,I still need a hotel reservation confirmation from March.17th to March.23rd.Sorry for the troubles.The reservation is only for Ms.Wang's visa.
