In connection with the SPG More For You promotion, you can earn 500 bonus Starpoints just for updating your SPG profile. This should not take more than a minute or two.
Here is what you have to do:
1) Register for the SPG More For You promotion at www.spgpromos.com/moreforyou by November 30, 2014 by entering your SPG number and email address.
2) Update your stay preferences on your spg.com profile by December 15, 2014.
Although the SPG More For You promotion requires a stay to earn triple points, you do not need to complete a hotel stay to earn the 500 Starpoints. But you still have to register for the SPG More For You promotion before updating your preferences.
Once you register for the SPG More For You promotion, you will be asked to update your preferences.
If you are unsure if you have registered for the SPG More For You promotion, just register at https://www.spgpromos.com/moreforyou/ again and SPG will let you know if you have already registered.
Although you can update your profile by December 15, the deadline for registering for the SPG More For You promotion is November 30.
500 Starpoints is not a lot, but this is an easy way to earn them as well as extend the life of your Starpoints if you have not had any activity in a while.
