关于Bergen YMCA Hostel的预定，请各位指教：）

今天在预定Bergen YMCA Hostel时收到旅馆的邮件回复如下：


To make this Booking please write back to us with your credit card number and expiry date (Visa (not electron), Bankcard or Mastercard) and your arrival time.

We do not make any Booking until we have received all details and we will then send you a confirmation email with a reference number and our cancellation policy. We do not take payment beforehand unless you are a late arrival. The card is used as a guarantee for our cancellation policy.


因为订其他得hostel没有遇到这种情况，一般都是先支付10%的押金。想请教有经验的达人们，把自己信用卡的信息事先发给旅馆，是否安全呢？


非常感谢！
