The timing and list of non-participating properties is perfect for me. It looks like I'll be in Sydney for Jan and Feb and with none of the 3 Sydney properties participating I will be able to concentrate on the 58 more nights I need by May 31st for my IHG Sweet Dilemma bonus of 160000 points.
If the Sydney properties had been included I would have been torn in 2 directions- now it will be an easy choice!
