My son had a Mickey and Friends party when he turned 5. It was so much fun!!! Let me share what we did, and see how you can taylor it to little ones, and a much smaller group.
We did a Mickey pull-string pinata, so when the kids arrived, I had them decorate a brown paper bag with Mickey/Disney stickers. They used the bags for their pinata loot.
I had a craft. We made Mickey and Goofy out of toilet paper rolls. Perhaps you could do something really simple like have them make Mickey puppets out of brown bags. The kids could color them, and the parents could cut and help them glue the pieces on. I did a search for Mickey crafts, or something like that, and got tons of printables and craft ideas. And yes, they did have plenty of printable coloring pages.
We played pin the bone in Pluto's mouth. You could do something similar with a Mickey theme. Draw Mickey on a posterboard, and have them "pin" on his ear or something like that.
A big hit for all ages was a Mickey and Friends hunt. I set it up like an egg hunt. I got little balls, and put Mickey and Friends stickers on each ball, and hid them (you could just scatter them or hide them really easy for little ones). With the older kids, they had to find one of each friend, but the little guys would love just finding the balls.
And perhaps the biggest hit, which every age LOVED, was our balloon drop/dance party. We got one of those balloon nets that drop balloons when you pull the string. We have the video Fun and Fancy Free (Mickey and the Beanstalk). At the end, they have a Mickey music video (I can't remember the name of the "real" song it is made after). We played the video and dropped the balloons, and the kids had so much fun.
Have fun!
