The fastest way to add to your elite nights if you dont have it already is the Chase Marriott card. Not sure on all of them but the black one gives you 15 elite nights/year as a perk, which would quickly vault you up towards plat. for the year.
For lifetime status you can look at https://www.marriott.com/marriott/rewards/elite-benefits.mi
|Lifetime Silver Elite||250 nights + 1.2 million points|
|Lifetime Gold Elite||500 nights + 1.6 million points|
|Lifetime Platinum Elite||750 nights + 2 million points|
zukracer you must have gotten me by a mere few seconds........nicely done!
You can get to Platinum faster by spending a lot of nights in a hotel and or spend like crazy on your Marriott Credit card!! Here are the requirements to achieve lifetime status in MR, but you will have to call Customer Service to learn how many points you have earned in MR. Your total nights are listed in your MR account.
Best of luck attaining these levels.
Marriott also has a "Taste of Platinum" challenge that might work for you. You can start this challenge whenever, but I'd recommend doing it like the second day of a month before you think you might have several stays coming in the next 3-4 months. It used to be that it took a specific number of nights stayed during the full 3 months and the partial month that you started it, but now I believe it's a specific number of stays, instead of a number of nights. You get promoted to Platinum for that time, and if you meet the stays needed to match the challenge, you keep the Platinum status for the remainder of the year, and then a full year after. Contact Customer Care and ask about this. Here is a link to a newer article that might explain it a little more, or let me know if you have any more questions.
