I don't understand why people advocate against taking kids to Disneyland because they "won't remember it." Maybe they won't remember specific details when they're 30, but their brains are developing big time during these years. The stimulation, fun, and bonding with parents and siblings during something like a trip to Disneyland is priceless.
The logic that dictates that it is useless to take a toddler to Disneyland because they won't remember it would also dictate that it's useless to take a toddler to the park, and I can't imagine that would get much traction.
Also, not everyone forgets everything from before they were 5. One of my fondest memories of my late grandmother was watching the Main Street Electrical Parade with her when I was 2-3 years old. I remember it vividly and tear up whenever the song pops up. Its the main thing that comes to my mind now that she's gone, even though I had many great experiences with her growing up.
I also remember my great grandparents and other grandparents who died by the time I was 3, I remember them very fondly, and I'm glad my parents didn't decide not to take me to see them because I "wouldn't remember it anyway."
