I understand the interest in avoiding the crowds, but for the most part the views of WoC from the VGC are not that good. You're missing all of the projections on the water screens and the proximity to the show. Unless you're agoraphobic I'd make the effort to get to the show early, bring a blanket to sit on, send someone off for goodies and just wait. I've seen the show from the viewing deck at the VGC and from the show itself and there is no comparison.
There are two meal packages that get you WoC FPs so that you don't have to get there first thing in the morning. There's a dinner package which is pricey but gets you standing area right down in front. (Assuming you get there early enough to claim your spot.) There's also a picnic package, which is about $15, and includes a good viewing spot. However, if you don't get there early enough to claim a good spot within your viewing area, it is still a problem. Some of the show is right down on the water, but much of the show is up in the air and any viewing spot that is in the FP area will be fine. Unfortunately, side views just don't give you the same effects.
