If you bank 2015 staroptions, could they still be used in 2015 or do you have to wait until the next year?
Once you bank them, they have been move to the next year, and are not available in the current year - during the process you are told that it's irrevocable.
But you don't have to wait until the next year to MAKE a reservation, you just make a reservation that is IN the next year.
In other words, as soon as you roll them over (from 2015 to 2016) you can make a 2016 reservation - under the regular Staroptions reservation rules - 8 mos. before check-in.
So right now, the Staroption reservation window is open for Jan. 1 - June 7, 2016.
With Starwood, the "year" on the Staroptions refers to the use year, not when you can
initiate a reservation.
