You need to create a memory of Disneyland. Few 3, or even 4, year olds can remember things very long. I would suggest waiting until the YOUNGEST is at least 7or 8.
That way they can both remember the experience into adulthood.
Disneyland is not doing the free admission on your birthday anymore. Sorry! In my opinion, I think the youngest should be at least 5 years old to understand what's going.
So that would make the oldest 8, correct? This age he can still experience the magic without it being ruined. My first trip was when I was 9 and when I went back at 10 1/2 I started connecting things and it wasn't s magical.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
