I tend to agree. Those of us who frequent Disney and theme park discussion boards and who visit quite regularly may or may not find elements of NextGen attractive or particulary useful, but we are not typical guests. Over a period of a month at work, I casually chatted with 14 people I know who visited WDW within the past 3 years (from 'way up here in Canada'). Since I am the 'Disney Guy' on staff, people will ask me to help plan trips for them, tell me what they liked, vent about what they didn't like, etc. Many of these familes are planning return trips (some in 2013) and they represent what I would call 'casual guests'. They'll go to WDW in 2 to 5 year intervals, don't know the names of all the attractions, have never been on any WDW boards, etc.
During our discussions, I noted a couple major elements of NextGen...fastpass+ and RFID braclets to hear what they thought. Without exception, every person thought these 2 things would be awesome! The most attractive element for all these people was the idea of reserving ride times. The gist of the comments was this: 'We don't go there that often, so it would be the best thing ever if we knew for sure that we could ride our fav attractions before we left for the parks. That would be so cool and allow us to relax and not feel so stressed or rushed. We could go whatever time of day we want too, and as long as we booked in advance, we could still do the things we like best'
I'm not saying that billions couldn't be better spent, but I think Disney is ahead of the curve here and 10 years from now this might be looked back on in a much more positive light, as a bold, progessive move.
