Actually, and according to my experience ( I have been about 3 times) I don't think babies and small children do enjoy Disney or any huge park where you have to walk and sweat a lot, get into crowded bathrooms to have the chance to change the baby, etc....EVEN during NOT a peak season, Disney was crowded. Probably is just my experience, I just know that when the kids are over 4 years old (some get scared with the tall Disney characters all around) may be older...they have so much fun and really enjoy these parks with so much amusement and even ourselves like grown ups have a really good time.
Some other families may have had a good time with little and small children, I don't know, my sister in law did it..and she said it was fine.
Mc Mama, just be sure you have plenty of water and several breaks to sit down. You WILL need the stroller, and very comfortable casual shoes......
Take care,
