Well, there are two lines to be seated for CP......the first line is those that have the badges/tickets that are given out after you have eaten and paid for you CP dining package. That line is seated first.
Then IF there are any seats left, 15 minutes before the show starts, those who did not do the CP dining package will get to fill in the empty seats.
It is recommended that if you are in the second line, without the badge, that you should get in line at least 1 hour before the show starts, earlier for the later shows.
But...it's also said that you can hear, but probably not see, the entire concert from outside the Pavillion.
So it really depends on what you want.....a guaranteed seat requires a CP dining package.....a chance at a seat requires standing in line for quite a while with no guarantee that you'l get a seat anyway.....and being willing to stand outside and probably not be able to see the speaker or choir, means just show up before the show starts, lol.
