Omni Hotels typically require guests to be at least eighteen years of age to book a room. This is a common practice in the hospitality industry, as it ensures that the individual responsible for the reservation is of legal age to enter into a binding contract. In some instances, specific properties may have additional age requirements for certain accommodations or events, so it is advisable for guests to check the details for the particular Omni location they are interested in. While Omni Hotels does not have a universal policy that applies to all hotels in its chain, it is always recommended for potential guests to review the terms and conditions provided on the official Omni Hotels website for accurate and up-to-date information regarding age restrictions.
