Lugnut...They are revamping the Cali Adventure because they HAD to. They cheaped out on it initially, and that cheaping out bit them in the butt. You pointed to Space Mountain as being better, but fail to mention that DW is revamping its Space Mountain attraction this year. You also don't mention all of the attractions that California DOESN'T have, nor the hotels, restaurants, etc. One could make a very good argument that California has been the park that has been cast aside in favor of Florida over the years.
I am in the group that feels that there have ALWAYS been people who said "things aren't what they used to be." Heck, my dad is in that group. He's been saying that every year since our first trip, which had to have been around 1980. But let's think for a minute. At the time that he started saying that, all we had down in Florida was Magic Kingdom and River Country...and I believe two hotels. Since then, we've seen the introduction of Epcot, Animal Kingdom, Hollywood Studios, Downtown Disney, two water parks, many hotels, and much more. Yet to some, while the options are going up, the quality is going down, and down and down and down. If you had told someone in 1980 that they'd have ALL this to look forward to, they'd fall over. Although I think parks like Animal Kingdom and Hollywood Studios have room for improvement, I still laugh every time my father points to a stray piece of litter on the ground and says "It isn't what it used to be." In his mind, litter used to vanish before it hit the ground and cast members used to all but carry him from ride to ride. I went to Disney last April (and bought into DVC while there) and found it to be just as magical as the first time.
One thing that I think drives some people to say "it ain't what it used to be" is people's aversion to change. Disney could add five attractions, but if they close one that you liked, then the change - all change - is bad. They could add five items to the menu of your favorite restaurant, but if they take away the one that you liked most, then it was obviously some cost cutting measure that ruined your vacation. Something like Disney Vacation Club is GREAT if that is what you are interested in, but it is the devil if you have no interest and are annoyed by the placement of the kiosks all over the parks. Free dining in the fall is GREAT if it finally makes a Disney trip affordable to you, but it is an annoyance if you are a DVC person (not eligible for free food) and you find the parks to be more crowded because of the giveaway. People complain if a ride isn't refurbished, yet they complain IF it is being refurbished during their trip.
I don't pretend that Disney is perfect, but if you compare it to my last four trips, it kicked each of its butts:
1) Alabama: NO comparison to Disney. We were there for a sporting event that took place in a dilapidated stadium. Nice hotel, but few dining options.
2) Cape Cod: It was pretty and quite affordable, but once again, it was no Disney.
3) Jersey Shore: We had a great time, and our hotel was great, but aside from the huge expanse of sandy beach (much bigger beaches than in Cape Cod), it couldn't compare to Disney.
4) Hershey Park and Lancaster County: I love the Amish area, and I love Hershey Park, but Hersey Park is definitely a few notches below Disney. No comparison!
