Just to elaborate for any first timers or WDW vets who are planning trips... WOC dinner packages are pricey, so if you're trying to keep your food purchases within a budget and don't specifically want to eat at Wine Country Trattoria or Carthay Circle, just get Fastpasses.
In my opinion, viewing for WOC is a little confusing. They have several entry points set up. The Fastpass entry points queued up well before the show. However, they don't label or let people queue in the dinner package line until it actually opened. Carthay opened before WCT, so all the next to the railing spots (both in the wet zone and not) were already taken when we were let in, even though we were like vultures waiting for them to open our entry. Annoying, confusing, and/or cumbersome viewing is a huge minus for me, which is why we've only seen WDW's Fantasmic three times in the last 5 years/9 trips. Of course, now that we've seen Disneyland's Fantasmic, it will be even harder to justify seeing WDW's for a long, long time.
