Definatly check Steve Soares' site before you leave. They update every week so you won't know the exact times until that week, but it will give you some idea. I do know that for the past couple of years, it has been having the first show of the morning between 9:30 and 9:45m (depending on the time of year) and then doing another every 60 minutes through mid afternoon and then picking up in the late afternoon or evening after the 3pm parade.
