Days Inn generally requires that guests booking a room be at least 18 years of age. This policy is fairly standard across many hotels to ensure that those making reservations have the legal capacity to enter into a contract. Additionally, some locations may have specific policies that can vary, so it is always a good idea to check the individual hotel’s requirements before making a reservation. Guests may need to present valid identification at check-in to verify their age. If you would like to find information about specific locations or have particular inquiries, looking at the official Days Inn website may provide additional details or contact information relevant to your needs.
