刚发邮件预定Te Anau的BBH，得到了答复，有点不确

我在发邮件时问道：
I assume that the rate for a twin room might be around $42 per person.
If possible, I will be very much appreciate it if you could give us a lower price.
Thank you.

对方在邮件中答复：
Our twin ensuite room is currently available on 10th February 2013. Price will be $84 cash as you say you do not have BBH cards.

As we take cash we don’t need your credit card for the Booking

Tell me if this is OK or ask questions.

店老板说的$84应该是指两人合计84吧，英文不太我，也不熟悉新西兰人的说话习惯，帮我看下，谢啦。
