If you have an rci weeks account with other weeks, you can leave it in and just know that it isn't available for deposit. If you want to clean up your account, you could let them know on chat to remove it. If it is an rci points week, I would let them know on chat or just let it disappear if it is your only week when you don't renew your rci account. I would let them know you are discontinuing your rci account so they don't try to auto charge you (they do this in points). It doesn't charge your card but keeps your account open with a deficit.
