I know many of us like to think otherwise (with comments about how we may lose our jobs but are still looking toward a Disney trip), but Disney is a luxury and it is priced appropriately. Very few people pay that $82 number and if you compare it to the gate price at your average Six Flags (about $50, a number very few people actually pay as well), it's reasonable. I would argue even with the cutbacks of late, Disney is at least 60% better than a Six Flags (which has also made cutbacks).
Prices will always rise, and if people could afford $79 in 2010, they can afford $82 next year. If your budget was so tight that $3 is the difference between going to Disney or not, you probably shouldn't be planning a Disney vacation anyway.
