Can I check in at the hotel I booked today at seven the next day?

Yes, but you must check out at twelve.

There is no uniform standard for check-in time in the hotel industry. At present, hotels in most cities are implemented in accordance with international practices. The check-in time of the hotel is14,00, and the check-out time is noon12,00. Staying in a hotel for one night generally means after the day of check-in 12 and before the next day 12. However, due to the different service hours of rooms in major hotels, some of them can check in after 6 am and check out at noon 12 the next day. Some people have to stay after noon 12 until noon the next day 12. If they check in early, they need to pay half a day's rent. However, some hotels can postpone their check-out until 1 or 2 o'clock the next day, mainly depending on the relevant regulations of the hotel. Before booking, you can call the front desk to find out the hotel check-in rules, so as to arrange the itinerary reasonably.
