I like the Flying Carpet spinner, it's great for little kids and gives you a nice view to that part of the park, I just think the ride itself looks terrible. The 90's cartoony look of it doesn't fit in with the "naturalistic, 1970's, jungle/tiki bar" vibe of Adventureland... kind of like if they turned WDW's Splash Mountain into a New Orleans theme? wouldn't really fit in with the old west stuff around it.
I would hope/believe they would change how the Flying Carpets look, The Star Jets became The Astro Orbiter and Dumbo had at least 2 other versions/looks at WDW. If it had some darker colors and looked more like the Cave of Wonders, surrounded by treasure and jewels, I think it would fit in better with the Jungle look of Adventureland, much better than that boring, beige "dessert look" it has now.
...and if they pulled the "Song of The South" characters out of WDW's Splash Mountain and replaced them with "The America Sings" Sam Eagle, Ollie Owl, Rock n Roll Stork, and all the characters in Disneyland's Splash Mountain, I'd be fine with Splash Mountain becoming "America Sings the Ride". I like the look of the scenes in the ride more than the individual characters.
Most people seem to like "The Theme" of the lands in Magic Kingdom, don't know why Disney doesn't seem to get that before they change or add something to the park. Disneyland is like a Flea Market of different IPs, but Disney World is about the themed world/lands/environments and stepping into an immersive experience
