I didn't think they'd get it done that quickly! It's looking spectacular! These refurbishments remind me of Project Sparkle in DCA, where they're refurbishing pretty much everything to make it look new -- as if the park had opened for the first time.
Isn't that exactly how it should be at Disney Parks? At least WDI and Disney always say that in their books and presentations- They have a name for that, it's called project Main Street, which means that everything should look brand new. I know it's hard to achieve that, but at least three Disney parks world wide are able to that - TDL, TDS and DL Anaheim.
The submarine looks great. Hopefully they refurbed and improved the inside, too.
