I can't give you the adult 70's view either...but I'm a little older than you, and my first Disney World visit was the month it opened in 1971. I've been to Disney at least once a year since 1971, with much more frequency once my family moved to Florida in 1976.
I certainly remember the first days...though strangely the park itself didn't seem to make many changes for the first few years - the thing that sticks most in my mind is the evolution of the surrounding area. I can remember coming in on SR7, since no highways cut down there at the time...it was such a thrill taking that road trip from New Jersey, and entering what felt like some seriously old-fashioned southern country compared to our urban jungle up north. But Disney World brought tears to our eyes when we finally got there. The anticipation was huge right from the trams in the parking lot. The only disappointment was running out of E-tickets on the first day or two and begging the parents to buy us more. Yet I still had fun even on the A rides...as a matter of fact, one of my favorites was always the free 'If You Had Wings'!
Change-wise - the biggest upgrade of all was the evolution to park passes with unlimited rides. I remember that was big - for us kids, that was akin to living when electricity was invented.
I also love the evolution towards more Disney resort hotels available, so the trip to Disney can be completely immersive without the cheesiness and congestion of Kissimmee and the 192.
Service-wise, I've come to appreciate as I've gotten older the increased availability of upscale properties, rooms, and restaurants. I like the option to spend a little more for a nicer ambiance, maybe a quieter experience, more gourmet foods, a larger room, and a break from the kid-tensive atmosphere.
While I wouldn't necessarily consider changes Disney has made 'bad', since they are doing what is typical and normal to survive and remain profitable in a changing society. I would say my disappointments lie more in the changes to society - shorter attention spans, less courtesy, everything having to be bigger, louder, faster, brighter to please an increasingly demanding culture that doesn't want to go through the tedious process of paying attention to details. And educational displays and rides have had to fade back in place of more direct-marketing rides or fast-paced action rides - a disappointment for a school-loving nerd like me who always enjoyed learning experiences (Epcot blew me away when it opened - we were there opening day - and became my favorite park then, and forever more).
Golden-year wise - tough call. There's something good to be said for many different eras. I guess I'd have to pick mid-eighties if I had to hone it down to one time period. The 'old' Disney rides and attractions were still going strong, the ticket-system was replaced by passes by then, Epcot had opened to offer more options, the MK resorts were gorgeous, Fort Wilderness was a great way to feel like you were staying in Frontierland, and the crowds were not as heavy or intense as they can be today.
I never felt like Disney was stagnant or regressive. I guess the Disney magic works too deeply in my veins, but through all the changes, it never felt stagnant or dead to me.
Current direction of the parks - some good, some bad. All changes are understandable, and perhaps inevitable, but I'll still miss some of the original rides and themes as they are being replaced more and more by movie-themed decor, rides, and overhauls. I really wish it was possible to leave Magic Kingdom the way it was 20 years ago, and call it 'Classic', then maybe open a new theme park where you can fill it with Captain Jack, Nemo, Incredibles, Monsters, etc. I love those movies, and thoroughly enjoy some of the rides - don't get me wrong. I just wish they didn't have to replace some of the classic beloved rides. And I would have liked to see all of the direct-marketing banners and ads, decor, P.A. announcements, etc at a shiny new park just for that purpose, with a classic-style MK. As I said, the changes are understandable as society changes...but those would have been my preferences if I was given the reigns of the park.
For the good, I would say sometimes Disney's changes and refreshenings are good - they keep the park fresh and current, and as I mentioned before, bringing in more options for adults to enjoy themselves within Disney World without kids is something I thoroughly appreciate now...and something that really didn't exist in Disney's original days.
I think Walt would be proud that his spirit and intent lives on, and what he has created, no matter how large or different it has become, still brings together people of all ages, sizes, religions, classes, and colors in a happy, friendly, clean environment. And the parks have continued to be a beacon for family entertainment, a mecca for tens of millions every year, a happy place.
Walt might not have liked the pricing so much - even adjusted for inflation, it can get hard on 'regular' families like the one he grew up in. And though he would always have connected his movies with the theme parks, I don't know that he would have marketed them so prominently even in advance at the parks. And I dare say that Walt might be a tiny bit disappointed that the parks are allowing social pressures in the country to restrict the freedoms of some groups of people because they don't fit the ideal social mold (smokers, for example, not having any optional places to stay on property where they can smoke. And before anyone jump to conclusions - I'm not a smoker, never have, and never will...I just don't think that it would be too hard to designate one small building in a few of the resorts that have separate buildings a 'smoking' building - and keep big gates and fences and skull-and-crossbones signs around it so no non-smokers stray anywhere near it! Especially given that Walt was a smoker).
For me, the Disney magic remains alive - there are enough good changes to outweigh the bad for me, many more options for me to enjoy within Disney World, and still a friendly happy safe place where people can enjoy being.
More change will come - it's how Disney stays on top and continues to entertain and please new generations while still keeping enough of the classic atmosphere and fun to retain previous generations. I'll keep going with the flow too, no matter how old I get...I always can't wait to get back to Disney World, even when I just left.
Starting tomorrow evening, I'll be there again.
