我发邮件问过酒店了,不用管,就按照预订价入住。
Thank you very much for the inquiry.
Regarding of StayNavi, this coupon can only apply for the residents in Japan, we are very sorry to inform you that you cannot apply for nor use the coupons at present.
In addition, your room rate will not be changed for this situation.
As a result, you do not need any other additional operations, just check in as normal will be fine.
