Marriott has a program called LifeTime status. LTS is the result of many years in the Marriott Rewards program and the benefits/earned entitlements given to those people that have stayed loyal to marriott over nights and years.
There are three levels of LTS: Silver, Gold and Platinum and is based on the following criteria.
1. Years in Marriott Rewards Program-12 years.
2. Year at Plainum level-at least 1 year.
3. Nights: 600=Silver, 800=Gold, 1,00=Platinum
4. Points: 1 million=Silver, 2 million=Gold, 3 million or higher=Platinum.
All of the four critriea will need to be achived in order to obtain Lifetime status. Which means, if you achieve this and NEVER travel again, you get the benefits of that level.
