For anyone even considering I totally recommend this! I did the Knott's shoot on Accelerator yesterday and I think everyone (with the exception of my friend who had never been on before) rode the coaster about 7 to 10 times. An exception to the rule, however, if if you never have been on before. My friend had not been to Knott's for 11 years so they attached a microphone to her, interviewed her, but that took most of the shoot time so she only got a ride or two. Everyone else just rode a ton of times all morning! It really was an awesome day and a group of us continued to hang out at the park for a few hours after the shoot! Awesome times!
I would like to second this...the shoot at Knott's was a great time. If the shooting at the other parks is similar, I'd recommend going if you can. Unfortunately I wasn't able to stay after the shoot.
To answer the question above, we were all at the shoot from about 7:30 til 10:00, so allowing 3 hours would probably be best.
