If you check your account on the website, it will tell you how many nights you need for 'Gold'.

I am currently headed to N CA for 12 days. Under the old program, I would have maxed out at 38 nights (have a lot nights rolling off whose age will be > 12 months at the end of June).

The website tells me I need 18 nights more to acheive 'Gold' under the program. I should reach that in July.

There's no promotion involved.
