Do I need to pay a deposit by credit card when checking into a hotel in Hong Kong?

Hong Kong hotels have different rules. In most hotels, even if you use a credit card to pre-authorize at check-in, you can only use the foreign currency channel. When checking out, cancel the foreign currency pre-authorization and then use the UnionPay channel to settle the bill. Therefore, according to your situation, first of all, you cannot use your husband's card, which is prohibited behavior abroad. Then, even if you have a UnionPay debit card, the hotel may not be able to pre-authorize it when you check in. To be on the safe side, you can call the hotel to check. No, you can only use cash. RMB cash is also acceptable.
