We saw world of color last night as VGC guests and I saw no reason to do a dinner package or jump through other hoops. We lined up for park entry at 9:20 and they began letting in resort guests at 9:30. By 9:45 we has our Fastpasses for the early WoC show and were waiting for rope drop at the park.
WoC was swamped early due do demand from local fans and the simple fact that SoCal pass holders only had a few days to see the show before being blacked out for the summer. Now that blackout dates are in effect, it appears pretty easy to get passes if you arrive at opening.
The sixth floor viewing deck is also an option but doesn't provide the best view.
