Read those threads and also remember that you're still "competing" with the other guests who have bought those packages for the seats. If you don't show up early enough to pick out your seats with the Fantasmic Dessert package, you can be sitting behind a really big guy and have poor viewing. The same goes with WOC, you get the prime, center viewing area, but if you don't show up early enough you can be standing behind a huge guy with a child on his shoulders. None of these prime viewing areas has just one row of viewing with guaranteed unobstructed views. With the Fantasmic Dessert package, you can check in, get your assigned seats, then leave and enjoy some more attractions before coming back 15 minutes before the show starts. WOC doesn't have this. You get in line, get your spot and wait. I don't know if the WOC dining is really worth it unless you plan on dining at that restaurant anyway. You can get great viewing--especially in the blue section, by getting your FP early and lining up early--like you would still need to do for dining (maybe not as early though).
