Ask my girlfriend's room number at the hotel front desk. She doesn't know I'm here. I want to give her a surprise. Will the front desk tell me the room number?

According to the laws of the country, if you don't tell your friend's name, the front desk shouldn't and won't tell you his room number unless your girlfriend specifically tells you at the front desk. The waiter said that if someone asks for you, you can tell him your room number. If your girlfriend doesn't tell you this, the front desk should not and won't tell you his room number. This is privacy, and this is how hotels treat guests. Integrity should also be respected.
