How can I get discounted tickets for Epcot in Orlando? How about Universal Studio?
Discounted tickets are sold by AAA to members. I am not sure if you have to buy them from a Florida AAA office or if you can buy them from your local AAA office.
There are "tourist centers" selling discounted tickets, though the discounts are pretty negligible. Any big discount should be viewed warily, as it likely has strings attached (limited hours of use, gotta go to a timeshare sales session, etc).
Multi-day ticket packages are available, that trim the cost per day.
There are resident discounts for Floridians, but these can not be scammed by out of staters, as everyone has to show proof of residency (DL, etc) the first time they enter Disney/Universal to validate their ticket(s) or season pass.
