I have had 10 stays so far this year, all at international properties, at relatively high average rates.
Diamond amenity is random to non existing in many places (Dubai properties are a positive exception, so is HR Incheon), did not receive anything at all (not even a newspaper) this week in Sao Paulo and Santiago.
And overall one (I should say: My usual and much appreciated) suite upgrade at PH Dubai.
This, in combination with no G bonuses offered at any of the properties during my stays, does create an imbalance compared to North America. I usually very much appreciate the choice in North America, as the average international experience for me is significantly below a bottle of wine and a plate of nachos.
I also agree on the comments rgd. the credit card
