There is 1 Pandora store in the Walt Disney Studios Park : Hollywood Jewel Box.
A very beautiful store where I already have spend too much time:-)
It's usually very busy except when there are shows or parades.
Then most shoppes are a little less crowded.
Be aware that not every store has the same collections and it is possible you have to go to all the stores to find the charm you want (need).
But it's a wonderful walk and you will surely find what you are looking for.
