Can I check-in earlier than the stated check-in time?

As a rule, you can check-in earlier than the stated time if there is a vacant room at the hotel when you arrive. Webmytour.com cannot guarantee an early check-in early as it depends on the hotel.
Most hotels have a luggage room where you can leave your luggage free of charge before check-in. Some hotels charge a fee for an early check-in.
