Well I just went into the Diamond Lounge at Caesars Windsor in Ontario, and the lady goes:
"Oh, usually you need 50,000 Tier Points to get in."
"What? I just got to Diamond and this is the 'Diamond' Lounge"
"Yes, but you need 50,000 Tier Points to use it usually. Since you've played a lot the last 2 days you can come in, but if there's ever a line you won't be allowed in."
What a sick joke.
