So you think that you noticed, but the people at the site every day, and are building a mega million dollar mountain wouldn't have noticed? And you think Disney doesn't know how to get the most out of every dollar?
Let us remember that Splash isn't themed all the way around.
Let us remember that Tower of Terror had to have theming added when Fantasmic went in so you wouldn't see the show building.
Let us remember that (the queue for) the RnRC is set up so that you can't see the show building.
If you are going to complain about theming that is missing from backstage or from outside the park, you are way behind.
