Marriott Rewards offers program sign ups at the Silver level (lowest Marriott status level) for employees of many corporations and I wrote about this last time in 2012, but the participating companies and sign up process have changed since.
The benefits at the Silver level aren’t that great, but it qualifies the member for elite discounts, some guarantees and extra bonus points.
Here are the current participating companies:
Note that there may be other companies participating as well and that some of these sign up may require you to have company specific email address before it allows you to proceed.
If you are planning to do the Marriott Gold or Platinum challenge/status match (read more here), it may make some sense to sin up for the Silver first.
