Just had to reply with a minority vote. We're not OKW members, so we do just the opposite. Book at VWL at 11 months, then switch to OKW at 7 months. DH much prefers OKW, and fortunately we've always been able to get it at 7 months, hope that will always be true since he said once (hope he was kidding), "I'm not sure I want to go unless we can get OKW."
