No surprise there, the best spots for watching/photographing the Studios' fireworks are outside the park. Thanks for the heads up, though.
Disney has long struggled with the style/design of its hotel rooms, especially at the Deluxe level. I think part of this is the inherent tension between theme and luxury. Part of it is just awful design choices, like the continued use of wallpaper border.
With that said, I think the refreshes at the Deluxe resorts in the last year or so have largely been improvements. Gone are the visually busy and cheap looking bedspreads and going for a cleaner look with the white bedding and runners. The new bedding is actually fairly nice (nicer than what they were using), and this style is becoming the industry standard for luxury hotels. I could go for a nice duvet, but it's an improvement.
In general, I think the re-designed rooms have better balanced theme with a design fitting of hotels at these price points (the Villas at Wilderness Lodge are especially well done). I feel like a lot of this might be trickling down from Aulani, which I think crushed it when it came to tackling the combination of theme and luxury, but maybe the timing is coincidental.
Disney still has a long way to go when it comes to its rooms being on par with real world hotels at comparable price points (realistically, they likely will never be at that caliber), but I think things have improved with the recent re-designs.
