Hey lalathegreat - never been but it's something I've really wanted / needed to do.
To echo allienoah's observation, I've found that the locations and number of meetings has been declining in my area. I read here about how it's a good idea to reach out to the contact ahead of time to verify the time and place of the meetings:
www.coda.org/index.cfm/your-first-meeting/After finding a meeting from the CoDA Meeting Locator, it is suggested you call the contact person to confirm the meeting date, time, and location.
I know that other members have told me they personally found it to be extremely helpful and critical to their recovery, and I've also had therapists strongly recommend it, so I would say it's certainly worthwhile to at least give it a try.
