I made my CP reservation the day they came out in late August . I got the last show on Xmas eve. Sadly on Xmas eve this show was rained out. Oh well, we will try again this year.
Last year MVMCP came out in late April, but CP did not come out until August. I think they waited to see if they were going to have 3 performances per night, the year before they cut to 2 on weeknights (after 9/11). They did end up doing 3 per night, everynight last year.
They are smart to release them early, then they can collect the money earlier.
