We buy postcards every trip! We don't mail them, but we keep them or give them to my grandparents when we get back or just put them in the scrapbook.
I feel like this guy was just naming all the things that make Disney charming, but making them sound horrible.
So the pay phones...what if your phone goes dead and you don't have your charger? I have used the pay phones once in the parks with my dad before I had a phone or he even took his phone into the parks. And because I loved taking pictures my mom bought me one of those little Kodak plastic cameras so one of those camera stores might have been helpful then, but maybe not so much nowadays.
And just stopping the water pageant and throwing it in the dumpster? That's like doing that to a classic attraction or parade in Magic Kingdom! Oh wait.... And sure, maybe people aren't booking the MK resorts for this little nighttime spectacular, but what about the people paying $40 a pop for a late Chef Mickey's dinner, or Ohana, Cali Grill, Kona, the Wave, Narcoossee's, Citricos, Victoria and Albert's, any of them, and they happen to walk out on the dock to head back for EMH at MK and they see a sea creatures and a giant patriotic spectacal over the lagoon, and then they come back to share it generation after generation, ultimately given Disney more $$$
As for DisneyQuest, I've never been so I can't say, but anyone I've ever personally talked to has loved it, especially Cyber Space Mountain.
