Don't know about Disney( but it would be nice. ), but Universal has a special deal through the end of April for cops, firefighters/EMS, active duty military.
The "Hero" gets in free, and gets a pass for free admission for 4 out of the next 7 days, and up to 5 family/guests get admissions for 50% off.
I used this TODAY coincidentally, and to get our group of 5 in (4 adult tix, 1 child (myself included)) for today only cost us just over $101. No other discounts inside the park, but hey, this alone saved us about $140.
A warning however: you have to fill out a couple of forms, and all members must sign their tix, and you must all enter the park together. The ticketing process is VERY slow. Get to the ticket booth EARLY (the far left one) (I'd give it at least 30-45 minuted prior to opening.) We got in line at 8:50 & entered the park at 9:25.
But the savings in $$$ more than make up for the inconvenience.
Have Fun!!!!
