Early check-in at hotels is sometimes possible, but it's not guaranteed. It depends on the hotel's availability and their check-in policies. To increase your chances, it's best to request early check-in in advance when booking or by calling the hotel the day before your arrival. Some hotels may offer it for free, while others may charge a fee. If the room isn't ready, you can often leave your luggage with the hotel and explore the area until check-in time.
