No. You said "how often do "refreshes" or "replacements" ever move the needle?" Those are your words. You are the one that brought up "replacement" correct? Technically Soarin "replaced" Food Rocks. By the way an "addition" can also be a "replacement." I guess it is impossible that a "refreshed" or "replaced" attraction contributed to the post 9/11 recovery?
I think you may have been confused when you said "refresh" and "replacement."
I wasn't confused, you're changing how I'm defining the word. By your definition anything short of a brand new land added to the park is a refresh. Something like Expedition Everest was very clearly an expansion to Asia but under your definition it is a "refresh" because Asia already existed. We're arguing semantics at this point, so that part of the discussion is done from my end.
Looking at new attractions (regardless of the classification of refresh/refurbishment/expansion), the most successful addition in recent years has been Expedition Everest. It came during an aggressive build cycle during the Happiest Celebration on Earth. It saw Soarin', Lights Motors Action and Everest all built within 7 months of one another.
May 5, 2005: Soarin'/Lights Motors Action
Jan 6, 2006/April 7, 2006: Everest
From 2004-2007 The parks grew in attendance at the following rates:
MK: 12.24%
Epcot: 16.28%
DHS: 14.58%
DAK: 21.67%
Something like Mission: SPACE helped Epcot, but not to the same extent. It opened on August 15, 2003. From 2002-2004 attendance increased signifcantly across the parks:
MK: 8.26% (14,040,000 to 15,200,000)
EPCOT: 13.53% (8,280,000 to 9,400,000)
DHS: 3.36 % (8,030,000 to 8,300,000)
DAK: 6.85% (7,300,000 to 7,800,000)
However, when you look at this in the context of 9/11 it took until 2004 or later for each park to match or exceed their 2000 attendance numbers.
MK: 15,200,000 in 2000, Didn't match that until 2004
Epcot: 10,300,000 in 2000, Exceeded that for the first time in 2006 (10,460,000)
DHS: 8,800,000 in 2000, Exceeded that for the first time in 2006 (9,100,000)
DAK: 8,200,000 in 2000, Matched that in 2005
