Here is a list that I gleened from several post hope they help
FREEBIES AT WDW
AK I got buttons at AK, and at the Living Seas for donating a dollar for the animals.
AK Cup Same thing at AK. I posted a picture a few pages back...Mickey is dressed in a Safari outfit.
AK We got lemonade, frozen I think, at AK when we got off of Kali River Rapids and it had a hard plastic Mickey straw/spoon in it. It isn't exactly free but comes with the treat.
All Every Park popcorn in each park comes in a cup/pail thing to go with each park
All BUS Honorary Bus Driver card from one of the bus drivers for "helping" drive the bus.
All At Guest Services of each park and Downtown Disney you can pick up a free "It's My Birthday" button to wear.
ALL If you have little ones that are too short for a thrill ride, the CM's have cute little cards to give them that basically say "you can ride when you're tall enough"
DTD I know we did some kind of contest (kids activity) at the pin store in DTD. I think it was answer a question. If the child did they got a great certificate with a pin on it!
DTD
Disney Store had a hula hoop contest and DD got a certificate and a choice of a pin.
DTD In the toy store in DTD there is a computer where you can design your own Mr. Potato Head. The picture prints out on a cute little postcard you can keep.
Epcot the kids can make a face mask for free by collecting things around the world.
Epcot when we asked for water for the kids, they came in plastic souveneir cups that said Epcot on them. make cookies for free in the "Land" pavillion in Epcot. each kid gets two cookies to take. It was fun! Look downstairs near the food court area.... it is off to the left.... a yellow blding front sponsored by Nestle
Epcot Then there's always the kidcot masks.
Epcot Ice Station Cool at Epcot - free drinks!!!
Epcot World Showcase Candy Lady in Japan makes free candy/sucker creations.
Epcot When you enter EPCOT, whether at the main entrance or International Gateway, look for a free children's booklet where the maps and schedules are located.
Epcot and Inoventions East I think ( I cant remember what side we were on) in the plastics exhibit where you make a robot and race him, once that's done you go and make your own plastic robot that you can take home.
Epcot At the end of Mission: Space attraction, you can send free e-mail postcards at the Postcards from Space booths in the Advanced Training Lab.
Epcot Free postcards at the end of Journey to the Imagination ride.
Epcot World Showcase KidCot fun stops, and each country (usually in a store in the country) has a desk and someone working it who gives that countries tags, the mask, and materials to color. Look on your guide map at epcot to find out where they are. In Mexico the kids could sit at a table to make stick masks and the CM who was there was giving out rolls of Spree candy when we were there. When you are done your mask take in to each country and ask a CM for a tag for your mask. Each country has die cut paper tags that will attach to the mask. In the end your kids have a nice souvenier of their 'trip around the world'. DD made it all the way around and gave her a cute 8 1/2 x 11" colorful poster as a reward for completing her journey
Epcot Buy a Passport in Epcot. Make a stop in to each park Guest Relations and ask if they have any type of "freebie" for the kids.
EPCOT I got buttons at AK, and at the Living Seas for donating a dollar for the animals.
EPCOT If you finish the KIDCOT fun guide in EPCOT they give you a small poster with the characters and the Epcot ball and "signed" by Goofy saying something about a great job, hope to see you again.
Epcot. Most restaurants give you a plastic cup. They used to be nice hard plastic with a cover and a straw but the last few times I ate at PSB it was a cheaper plastic cup that says Epcot on it with the characters.

MK I was taking a picture of my train-obsessed 4-year old when we got off the train at MK and one of the conductors happened to be getting off. He stopped to say hello to my DS and gave him a really cute card with Mickey and a train on the front. On the back it says "Walt Disney World Railroad Guest Conductor".
MK One last thing after riding on Buzz Lightyear, make sure to request your photo number, and get a separate card for each child. We didn't get the photo, but the back of the card has a great logo of the ride for their scrapbooks
In your room, they provide stationery and/or postcards from the resort. These are also great souvenirs. And don't forget the Disney Resort Pen!
