Marriott Bonvoy is offering instant Silver status for employees from various corporations before and they have just reactivated the campaign again.
Members that sign up with eligible corporate email addresses will have their account set up as Silver one instantaneously.
If you happen to work for any other global company, you can change the company name at the end of the URL address to see whether this offer is available for you as well.
This is an awesome offer, as to be qualified for Silver Elite status you need at least to stay 10 stays in one calendar year.
This status used to map to SPG Preferred Plus that comes with 4PM check out, complimentary internet and basic room upgrade. You can link your accounts and the SPG status is valid immediately once you have done it.
