What time is check-out for rooms opened at 6am?

Generally before 12 noon.

The hotel’s regular check-out time is before 12 noon, and rooms opened at 6 a.m. are no exception. This is because the hotel needs sufficient time to complete cleaning and preparations for subsequent guests. In addition, the hotel's policy usually clearly stipulates the check-out time. Guests need to leave the room by the specified time, otherwise additional charges will be incurred.

If you need a later check-out time, you can apply to the hotel front desk and get approval. But before applying, it’s best to understand the hotel’s specific policies and related fees in advance to avoid misunderstandings or disputes.
