We have taken Mollie and Emily to EuroDisney and Disney, Orlando several times.
Mollie 1st went to Orlando at 7.5mths - too young but she enjoyed the fuss, the swimming and it was as much for us as her.
Then EuroDisney at 18mths old plus me 6mths pregnant - she LOVED it, the junior rides, the characters and as it was early December - CHRISTMAS!
Then both the girls to Disney, orlando Mollie 23mths - LOVED IT and Emily 11wks - she couldn't care less obviously.
EuroDisney again when Mollie was 26mths - went crazy she enjoyed it so much, Emily was 6mths - enjoyed being with us all together but again not that fussed.
Disney Olando when Mollie was 3.25yrs and Emily was 18mths - both of them were full of it, they loved the characters and junior rides, the swimming, the food! In fact, Emily was so into the characters that we had to drag her away from them kicking and screaming most times!
Here they are meeitng Tinkerbel

And Emily with Daisy Duck

And High 5-ing Handy Manny

Sorry for the HUGE photos but thought they might show example of how much a little one can enjoy Disney (nearly as much as Mummy does LOL)
We are booked Orlando again for Nov this yr, girls will be 4.25yrs and 2.5yrs
