Hiya Carol. Call the Riviera direct for your room reservations. You can find the info on pg. 23 of the Fall '07 (the latest) issue of the club mag and at this post on the club message board. http://www.ccgtcc.com/cgi-bin/bbs521/webbbs_config.pl?noframes;read=27659

The important items from the posting are:

Everyone who is planning on attending the convention is encouraged to book the rooms by mentioning “The Casino Chip and Gaming Token Collectors Club” group rate when they reserve. The telephone number to call for reservations is 1-800-634-6753 in the continental US, or locally at 702-794-9412.

Since your intentions are to renew, I wouldn't worry much about when you sign up. You can do the room this weekend and go over to the club website and you'll find the link to convention pre-reg online at the homepage. You'll get an e-mail confirmation that way. That's the way I always do it and it's easy and never a problem. Deadline as I understand it is May 1, 2008. Be sure to be there Carol!
