Fairmont Hotels and Resorts typically require guests to be at least eighteen years old to check in. This age requirement is standard across many hotels to ensure that there is a responsible party in the room. However, there may be some locations that have different policies, particularly for properties that cater to a more specific market, such as resorts or facilities designed for families. In addition, guests may need to present valid identification upon check-in to confirm their age and identity. It is always a good practice to check the specific policies of the Fairmont property you are considering, as there might be variations based on location and specific circumstances.
