Double Free Night Credits Bonus at Omni Hotels

I signed up for every hotel loyalty program I could find as part of a research paper I am writing for class (8 weeks until I graduate!), including Omni Select Guest.  Today I found an email promotion for double free night credits on all stays before April 1st (not sure if it's a targeted promotion).  This isn't a status fast track bonus, but just a free night award fast track.  Even though I have no plans to stay at an Omni (I need SPG stays), I signed up.  You never can know travel plans for sure.

There's an Omni hotel in San Francisco
