My best days at Disney was the first time I went after having kids. The park takes on a whole new meaning then. Things I didn't care for before I love now because of my kids.
When my (now ) DS 15 was 3 years old and he ran into Minnie's arms for a hug at DHS.
Also have an adorable picture of my 2 older DS with Buzz and Woody - their favorite characters, and a great picture of all three with Mickey. Ah, those were the days when they didn't mind having their pictures taken.
I always get teary eyed watching the fireworks with my family.
