From my earlier post in this thread:
The representative also went on to say that they specifically made this year's promotion easier because of the troubles experienced with last years "passport" style program. Once your TR card is "opted-in", she reassured me that the TR system automatically keeps track of each destination that 1 base credit or more is earned at (specifically for this promotion). Yes, you can also opt-in at one casino in person for this promotion, but once you are opted in, there is absolutely nothing else you have to do other than make sure you get 1 base credit at a qualified property.
Lastly, I was told that the Reward Credits will be paid out by October 31.
If you are able to visit 6 properties, you'll have 60k worth of reward credits to spend
