I'll jump in for GeorgeD. And he can add if I left anything out.

Easiest way to get the CCA discount is to go to the club website (ccgtcc.com) and click on the link that says "Book Your Room at South Point Hotel" in the middle box on the 1st page. It takes you here:

You'll see that the discount code is: CAS0608

The discount rates are described as follows:

Casino Chip & Gaming Convention - 2025
Group rates: $90 midweek & $140 weekend. Rates below include daily resort fee & exclude taxes.

I booked through the link above and had no problem getting the type of room I wanted, etc.

Hope to see you there!
