How can I get discount tickets to Disneyland and Sea World?

If you belong to AAA, yu can try that way.

Also, the grocery store could have "Pay child fare for adult ticket" cards

Disneyland doesn't offer discount tickets, but the more days you buy on a ticket the less each day costs. If you are a resident of Southern California you can buy the $99 3Day Summer Fun pass either at the park or at local grocery stores.

I would not recommend Ebay or Craigslist as these are often scammers selling invalid, expired or duplicate tickets, or single days on a multi-day ticket where they demand the return of the ticket each evening. Disney is on to all these tricks and has the right to question you about your ticket purchase, previous visits etc and will confiscate the ticket if your answers don't match those in their system. Also, anyone over 10 using a child's ticket will be sent back to the ticket booths to upgrade to an adult ticket.

i think kiddies can get a discount oh and i don't think tickets from others are valid because once i used a ticket that my friend got me and disneyland and seaworld didn't accept it

there is a deal with universal and those places that you can like get a ticket package with all of them

u can go to craiglist.com and find people who selling tickets for cheap price but have to do it fast can they can be sold real soon and u can find more good deals

if you're military you can get some, otherwise the prices just went up at Disney.
