I'm on board with it too. It sets up the proper timeline for the narrative (which will clearly be explained in the ride).
Gringotts is cool, but not as in your face "take a picture awesome" as Hogwarts castle... this of course fixes that problem nicely. Every person that visits will have this picture.
If only they'd add two baddass dragons somewhere in Dragon challenge too (along with a Quidditch pitch), would certainly help solidify that attraction.

Don't forget Malificient though, especially the one in DLP. She's pretty badass too.
Oh and Figment... but that probably hits a nerve.
Edit again... there are more than I realized...
