The decor probably won't feel "Disney" to you, but let me tell you my thoughts. The CR was our first WDW hotel that we stayed in. In fact, I have stayed there several times as a child and when I think of WDW it is one of the first thing that comes to mind other than the parks. Here are a few things about it that make it "Disney" to me:
1. The monorail going through it. Others have said this already but I believe it is worth repeating. Where else can you ride on a monorail and actually go through a hotel? It's awesome! The image of the monorail disappearing into the hotel is one that stands out in WDW pictures/video over the years. The "hum" of the monorail while in the hotel is comforting (it's not loud...at least not that I recall. Of course, we were a few floors above. I imagine the first floor above might feel a bit different).
2. The round pool. I know it sounds dumb, but something about the round swimming pool makes me think of WDW. This was the pool I liked the most when I was younger and always looked forward to it.
3. The 4th floor. This is where you'll find Chef Mickey's, the stores, and the escalator/elevator to access the monorail. It doesn't get much more Disney for me than eating there with the monorail driving through every few minutes and shopping in the stores on that floor. Even just being on that floor brings back memories of waiting for extended family to meet us that were staying at the Poly on several of our trips.
4. The access to resort activities. There are so many resort activities available to Disney guests, but I feel like the CR has some of the best! Sailing, power boats, etc. It's all here. Of course, it's what we liked to do when we stayed back then. So I am biased. But for me, this is a big part of my memories.
5. The mural. There is this huge mural of a bunch of goats on a mountain. One has five legs. I always look for it (though I actually know exactly where it is as soon as I see it). It's just a tradition. Even when I am not staying there, I stop there and look for the goat. Why? Because it's cool.
I don't know if any of that helps, but this is what makes it Disney for me. Truth is, any WDW resort is Disney for you if you want it to be. It all comes down to preferences though. For me, CR is out of my adult budget so I won't be staying there again unless I suddenly strike it rich. Maybe later when my kids are grown, but for now it is everything I can do to plan our first family trip in a value hotel!!!
