That's correct. Once someone has started as part of the Invited Guest program, I've heard of them giving some incentives in the form of travel credits for joining sooner within the trial period. For example, if you join after one month, you get a certain dollar amount put in your travel credit bank. The dollar amount of the credit goes down the longer someone waits to join within the 6 month trial. But the credit doesn't come off the initiation fee.
