Yes, DVC is a timeshare. And yes, Disney is a business. WDW is a resort complex, there to make money for Disney (and its shareholders). But Disney has chosen as its business model making customers above-and-beyond happy (in return for above-and-beyond costs). So Disney "buyers" have a right to expect "Disney magic/Disney treatment." It's why some (many?) of us bought the product in the first place.
Under no circumstances (for a variety of reasons) would I consider buying "a timeshare." I bought DVC despite the fact that it's a timeshare--and the fact that it's Disney is THE reason why.
I took my son to Disney as often as I could afford it throughout his growing up years, long before I could afford DVC. And a huge part of the reason was in fact because both he & I love the parks & staying on property. But a huge part of the reason we love the parks and staying on property derives from how Disney treats us when we're there. I didn't (and still don't) begrudge the money I spent (spend) at Disney because the way Disney treats me makes me feel good--I like their product and I like the way they treat their customers (me)! I am (more than) willing to spend "Disney money" to get this.
So, not getting this "special feeling" IS a big and very valid reason for being unhappy w/the DVC (or Disney if paying cash) experience (whether on a cruise or at a resort). There are other cruises, other amusement parks, other timeshares, other resorts that I could choose instead of Disney if the "Disney magic" weren't such an important (to me) part of why I choose Disney.
So, OP, you have my sympathy. I don't blame you for feeling unhappy(ish) about the experience.
And absolutely this isn't war, death or pestilence. But we all have a right to be unhappy--and say so--about things that fall short of "the big bad things" -- I don't exactly resent being told (as a reader of this thread) that a disappointment on vacation doesn't equate to the death of a loved one, or a job loss, or whatever. But it was jarring--kind of condescending and a bit offensively "preach-y".
I sure hope no one reading this thread has to experience any disappointment in life--whether it's the "minor" kind that comes w/a disappointment on an expensive vacation, or a huge challenge like the death of a loved one. But it's the real world. Disappointments happen. And it's ok to talk about them, and say they're disappointing. At least I think so.
Hope your next cruise/DVC stay is as stellar and unexpectedly beyond-expectations wonderful as this past one was disappointing, OP...
