1. first time for this promo
2. yes, you can book hotels,get meals, and presumably score 300 USD if you find a property offering that one-for-two dollar (rare, not my best use of comp dollars)
3. I can guarantee in the world of social media, where twitter accounts are monitored by corporations, the trading of cards as described here, is known. The july 29 disclaimer pretty well proves that CET figured it out or was prepared for this. Enforceable: who knows. There is more down side to breaking customers bones over it than having what they wanted (higher traffic) come to pass.
4. Perhaps feeling as if you got over on CET makes you feel as if you can get over by gambling in their joints. Not a bad deal for CET.
5. getting a TR point for any table game is (excuuuse me) a crapshoot. Even if you ask, the boss who enters the data may have a bad day, not like your hair, or decide you didnt play all four consecutive hours. Or you get lucky. IMO, simpler to put the card in and make one five dollar bet. fini.
6. I dont own gaming stocks. I expect the bean counters make annual report entries about number of times a player hits the doors annually, on average, and this promo is likely to move that needle.
7. I think Lisa already figured all this out. Hiya!
good luck!
