We've taken DS1 when he was 14 months and 2 yo. For the very 1st trip I waited to see what DS's temperment was like before I decided on going (turns out he's VERY laid back LOL!).
We had utterly wonderful, magical vacations both times.
The memories I have of the expression on DS's face when he saw Mickey & Pooh for the 1st time will live with me forever.
I have a picture of DS (then 14 mnths) staring at the electric light parade, mesmerized, with DH in the background w/tears in his eyes. DS had just turned to DH and said "see dat daddy!!!, see dat!!!!!" I have it framed and sitting in the most prominent place in my living room.
On a bus ride home after Epcot's Illuminations one night, DS (then 2 yo) was sleepily nestled in my arms and whispered in my ear, "I am happy. Thank you Mommy". I'll never forget that.
No, I don't think DS will remember specifics from these trips. I never expected him to. But, IMO, they will shape who he is becoming; they promote family togetherness and love; they give us history as a family; and they give ME memories that make me cry (happy tears).
We do tons of things with our toddlers on a regular basis that they aren't going to remember, but it doesn't stop us from doing them. For me, why should Disney be any different than a trip to Six Flags (well, more expensive!

)
DS looks at his Dinsey photo albums at least weekly. He knows where Mickey lives and he knows when we are going back. He tells his 3 month old brother all about WDW and what we are going to do when we get there (according to him we will live at MGM's Dsiney Playhouse with Rollie Pollie Ollie), the plane ride, the pools.
We are heading back in feb '05 when DS1 is 4 yo and DS2 is 1 yo.
I cannot wait
