How much do new Disney attractions increase attendance at the parks?

I have a project and I need to know how much attendance at Disney is increased when they add new attractions. These three are the ones I need.



When Everest opened at Animal Kingdom.

When Soarin' opened at EPCOT.

When Rock N' Roller Coaster opened at MGM.



If anybody is able to find these numbers for me I will greatly appreciate it. Thanks.How much do new Disney attractions increase attendance at the parks?
My grandparents work at Animal Kingdom %26amp; for the first month that Everest opened the attendance doubled. As far as the numbers I don't know of a site unless you check out Disney.com or Allears.net.



I was working at MGM when Rock N' Roller Coaster opened %26amp; the attendance doubled if not trippled. I remember lines being over 2 hours long.How much do new Disney attractions increase attendance at the parks?
Of course there is no set number of people, but it increases quite a good deal when a new attractions is built. The numbers do plateau though.
