Yes.
My family went as the holidays in 2006
Me - Santa (Christmas)
Mother - Heart (Valentines day)
Sister - Leprechaun (St. Patricks day)
Sisters BF - Pumpkin (Halloween)
Sister - Turkey (Thanksgiving)
Father - Firework (4th of July)
It was tons of fun. I actually had to take pictures with little children. And I got a personalized note from Mickey with his Christmas list when we went to Toontown
It was great, we were very popular around the park. All homemade costumes
