It is relatively safe.
Ctrip credit card guarantee is a booking method, not payment. Only when the tourist fails to check in normally, the corresponding room fee will be deducted from the guaranteed credit card. Visitors still need to pay the room fee at the front desk to check in when they arrive at the hotel. The hotel accepts payment with another credit card or cash. If you pay with the same credit card, please make sure you have sufficient credit limit, because there is a handling fee for choosing to use frozen funds as actual payment, domestic credit card 1, foreign credit card 5.
Usually, reservations for five categories of hotels require credit card guarantees:
(1) Hotels in Hong Kong and Macau, China;
(2) Some central cities in the mainland Hotels in core business districts and tourist areas;
(3) Hotels in peak tourist seasons;
(4) Hotels around exhibition periods, such as the Canton Fair, China Fair, Food and Drinks Fair, etc.;
(5) If the hotel reservation arrival time exceeds the time specified by the hotel, such as the guest arriving late, it exceeds the latest reservation time (usually 18:00).
