Hello,
Sorry, yes, TL=Tomorrowland.
As far as TDL, no, you are not making things up!
In 2001, where TDS did not open until Sept 4, TDL's attendance that year, again according to Amusement Business, was 17,708,000 and the most visited theme park in the world. It had held that record for several years in a row, with Magic Kingdom #2, and Disneyland #3. In 2001, Magic Kingdom's attendance was 14,784,000 and Disneyland's 12,350,000. In 1997 (last year for which AB archives are available), TDL = 17,368,000, MK = 17,000,000, and DL = 14,250,000.
WDW is sort of the barometer by which multi-gates are measured. If you look at WDW's attendance for last year, you see: MK = 15,170,000, Epcot = 9,400,000, Disney-MGM = 8,260,000, and AK = 7,820,000. These are pretty healthy ratios and sort of informal goal for other resorts. At Disneyland Resort, DL = 13,360,000 and DCA = 5,630,000, so DCA's is less than half of Disneyland's, whereas Epcot is about 62% of MK's. Disneyland Resort Paris is obviously even more dire where DLP = 10,200,000 and WDSP = 2,200,000.
On the other hand, you have Tokyo Disney Resort where TDL = 13,200,000 and TDS = 12,200,000. Only 1 million guests separate them and they are #3 and #4 respectively on the worldwide chart. It's been difficult to interpret the numbers. On the one hand, TDS is an unqualified success. On the other hand, you have the cannibalization effect and the pressure to maintain the success of TDS. This is the same problem that has affected WDW since AK's opening. In 1997, WDW's Epcot attendance = 11,796,750, Disney-MGM = 10,473,750.
BTW, Disney frequently likes to whine that WDW's attendance has still not recovered from 9/11. Technically this is true but not by much. WDW's total 2004 attendance was approx 40.65 million, whereas Y2K attendance was 43.2 million, less than 3 million more. Disneyland Resort's attendance grew from 13.9 million to approx 19 million last year, thanks to DCA.
One more aside (really), Universal Orlando's combined attendance last year (13 million) was less than Disneyland's alone.
