The minimum age requirement to stay at Diamond Resorts properties typically varies by location and specific resort policies. However, in general, individuals must be at least eighteen years of age to book a room. This policy ensures that an adult is responsible for the reservation and any associated obligations during the stay. Some resorts may require guests to be at least twenty-one years of age to check in, especially in areas where local laws dictate such rules. It is important for prospective guests to check the specific requirements for the individual resort they plan to visit.
