There seeems to be a targeted “Bonus Beginnings” promotion offering new Starwood Preferred Guests members the option of receiving either a $25 SPG Award Certificate or 2,000 bonus Starpoints after staying one night at any Starwood property.
Though neither Kevin and I are new members, I was able to successfully register Kevin’s account for this promotion, but not mine, so YMMV. Overall, this is a pretty generous promotion if you have an upcoming SPG stay coming up. I chose the 2,000 bonus points option because I value them at around $70. You may check your eligibility and register for this promotion here.
