If a stray fountain is going to spray me like a firehose anytime during the show, I of course would want to buy new clothes at a shop on Paradise Pier, but I would expect them to throw in the dry underwear for free. Just saying.
I personally love the villains sequence of WoC. The music becomes a little bit metal and trippy and the overall effect is just thrilling. If WDI wants to retool the show and the villains sequence, I'm fine with that. In fact, I would love for them to do a director's cut of the show next summer, but for everyone. I would think it completely fair if D23 got to see it first, with regular shows for everyone for the rest of the summer.
The subject of availability, I think, is the real reason Glowfest scored higher than WoC. Not everyone got to see WoC, but anyone could go to Glowfest. It makes the most sense. During the Food and Wine Festival, I didn't want to drop down $50+ to watch someone cook, but I loved the tapas counter in Stage 15 (?) because, even though I still had to pay for it, I felt like it was something I got to participate in without any stipulations. Sure, you have to pay for your glowing drinks, but you don't need a fastpass from the beginning of the day to walk in and listen to the music.
