I'm on the fence regarding whether or not it's still the trend.
On the one hand, there's a lot of snark online about "sad beige". Indicating the pendulum might be about to swing on styles. I hear that in some areas, big, bold, wallpaper prints are even back in. Never thought I'd see wallpaper again!
On the other, I think the faux minimalist (faux because it really just means people can afford storage space), open concept, natural pale colors palate got popular for a reason. I don't think it was a kind of random trend. If you think about what the word "stuffy" means, in the most literal sense, it means "full of stuff". There's a reason people associate cluttered rooms with "stuffiness" and minimalist rooms with a feeling of openness and relaxation. Probably especially true for those of use who grew up during the "collectibles era" of the 80s and 90s where the trend was literal stuff, like, everywhere. You bought cabinets and shelves and more shelves to showcase it. Marie Kondo was just waiting to happen. So again, I don't know if this is a "trend", or likely going to be people's preference moving forward in the era of bigger buildings with more storage space.
Either way, however, I think it's a mistake (I think... again, Riviera DVC sold really well so what do I know) to assume that people want to look at their living room or even their favorite beachside Hilton while at Disney. I think that look is more for where people go to just "be" - to sit around and relax. Home and beach lines up with that, Disney parks do not. As much as I try (mostly in vain,) to declutter my house at home, there are some places in the world I would love to see or visit again specifically because they are full of interesting things. Tokyo definitely comes to mind... Vegas... anything Disney related... Dubai... heck even just Great Wolf Lodge. All of those places strike me as having a vibrant, playful, endless exploration type element. Like imagine taking your kid to Great Wolf lodge and suddenly everything is beige, lol! There's a time and a place. I just don't think Disney is it - but again, maybe they know something I don't. Maybe people want playful parks but bougie themed hotels, who knows?
