Is your trip only 2 or 3 days? You can still get a discount. If you don't plan to "hop" from park to park on the same day, and if you have no plans to visit the water parks, Pleasure Island or Disney Quest, the one-day/one-park passes are your best deal.
This deal is only available at the theme park ticket windows. Buy your first day's ticket at the regular price. Either at the same time, or before the end of the day, show the one-day pass at the ticket window and buy your second day's ticket for $5 off. If you need a third day, you get a $10 discount ($5 per day). Total savings over buying three separate days' admission is $10.65 per adult when you add in the tax savings.
With these one-day/one-park passes you can only go to one park per day -- you can't "hop" from park to park on a given day. Also, the second day expires 4 days after purchase, and the third day expires 6 days after purchase. Still, it's around $25 per adult cheaper than the 2 or 3 day Ultimate Park Hopper passes, and you don't have to stay at a Disney resort to qualify for the one-day/one-park passes.
