Will the Beijing sites be extra crowded Oct 5-9?

We are planning to book a tour and arrive in Bejing before the tour begins. We will arrive on Oct 5th and have a free day on Oct 6th. Our tour takes us to the major sites on Oct 7-8 including Tiananmen Square, Forbidden City & Temple of Heaven on Saturday Oct 7 and the Great Wall in the afternoon on Sunday Oct 8th. Is this a bad idea because of the Golden Week crowds?
