For what it's worth, my first visit wasn't until 2007, when I had just graduated high school. But Tom Sawyer's Island over in Disneyland (near where I live) is a "must do" every visit for me. WDW's was similarly, simply because it still had an open fort at the end of the island so as a "Disneylander", this was something on the East Coast that I always liked to pop in and see (and leave through the hidden tunnel). Grabbing a snack and visiting the island while watching the river traffic go by with my wife is also one of my favorite things to do come mid-day.
As time moves on, I realize that any attempts I may make to change the minds of those at Disney or others online regarding changes such as these are moot. If it didn't work for Mr. Toad's and all the fanfare that movement got before the widespread accessibility of the internet, it's not going to work for me or the attractions I care about. Tom Sawyer's Island, DINOSAUR, Muppet*Vision 3D and probably many more of my favorites will disappear soon or have already. The parks continue their slow, inevitable march towards each becoming the same identity-less, brand loyalty center. Coming on here to express admiration for something now gone, share a joke or rant into the void helps a bit.
Everyone's breaking point is certainly different. I've told myself the healthiest thing to do once that threshold has been crossed at any particular park, is to simply never return and find other things in life to enjoy. Still, it's hard not to say something while watching something you care about get chipped away little by little, even if you know nothing you say will make a difference. DCA crossed that Rubicon for me a while ago and now the WDW parks are inching closer and closer to it, too.
Thankfully I still have enough left of Disneyland to focus my enjoyment on. I'm hoping nothing like this ever happens to the rivers here. As long as folks keep spending money on Fantasmic! dining packages, they might have a chance!
