never to young
we went for our first trip in 2010, my wife and i and our then 3 and a half yr old...it was perfect! he already knew most of the characters, could walk/ride in stroller good, we always had a snack ready and it was great....fast forward to our next trip (april 28th-may 5th) well be bringing our princess who will be just under 1 1/2 yrs old...she knows mickey pretty good as well as a couple others..were doing magic kingdom 3 of the 8 days, 1 pool, arcade, resort and dwntwn disney day, animal kingdom 1 day, epcot and hollywood 1 day as well...we figure magic kingdom is perfect for that age group and our son will be 5 so its primetime lol....were going in knowing we wont see everything (thats what nxt yrs for lol) so we should be good to go...everyones other ideas on here are great as well
