I am trying to find discount tickets for Disneyland Resort Park. Does anyone know if they give a percentage off military family tickets or where I can buy discount tickets?

No Disney does not give discounts to military that I am aware or saw the years we were in California. You can purchase tickets for Disney at the bases ITT offices that are usually very good deal as tax is worked into it. I know the ones in San Diego areas also have vouchers for hotels around Disneyland and you can get some great deals on those as well. You have to call the hotels and find out what ones have openings available for the vouchers and which ones don't.
