They don't open the turnstiles until AT LEAST 8:00, and sometimes it can be delayed. It was during our trip last summer and they didn't open the turnstiles until almost 8:10! It also gets crowded with all the other guests with PS's waiting, so you might be a little late if the gates open late. We were, and since they know the gates opened a little late, nothing was said, we were just escorted to our table. Also, the princesses don't start circulating until Cindy's is at least 50% full, usually a little after 8:30. We were out of there by 8:50, with our 8:10 PS and we got seated at 8:20.
