Don't get me wrong I like Universal, I just spent 6 nights there and stayed onsite. But the only thing little ones can do is the playgrounds, this gets very boring for parents after awhile and honestly I have good water playgrounds not too far from my house. Check the height restrictions for both parks and you can see the difference. YOu have to be 40 inches for the trolley ride.
Here is a sample day at the park from Universal when my daughter was 18 months. Curious George Water park for a while, Barney(beware it scared her at the beginning it goes dark and they start the show with loud exploding confetti) Barney is the whole reason we went to Universal. Did not do Feivals playground because it is the same as Curious George to me. O.K. done with Universal over to IOA. Cat in the hat(Very jerky she crashed into her dad and I who were seated on each side of her. Carosuel, If I ran the Zoo Splash Area, One Fish Two fish, got water in face even sitting on inside and hated it. Talking fountain in lost continent. Camp Jurasic is for older kids Almost everything is too high for little ones to reach, spent an hour there on Saturday with my older kids. Ship Me Olive another playground. I spent alot of time at the playgrounds because there is nothing else to do. No parades etc. Boat ride from hotel is great and food at Universal hotels is better. Also great pools.
Sample day at Disney with 18 month old-Jungle Cruise, Aladdin(also might get squirted), TIki Room(loud but my kids liked it), Pirates of the Carribean, Country BEar Jamboree(loved it), Woody street show, TOm Sawyer Island, playground by Splash Mountain(not great), Haunted Mansion, It's a Small WOrld, Peter Pan, Mickey's philharmonic, Winnie the Pooh, Dumbo, Carousel, Pooh's playground, Mickey's Toontown and their houses, Donald's water playground, train, Tommorland Transit Authority; Carousel of Progress, Buzz light year, Monster's Inc COmedy Club, SPectromagic, daytime parade, fireworks. There are also many child friendly things for toddlers at the other disney parks. I disagree that toddlers don't like rides. Mine loved all of the above, except getting squirted on Aladdin. What makes Disney so great with a toddler is the memories you make with your child. Seeing your daughter see It's a Small World for the first time is priceless. At Universal yes you could entertain your daughter at the the splash areas but that is about it and if there is any sign of rain/thunder they close the plash areas( This happened at some point to us almost everyday last week. Disney still has alot to do if it rains.
You are really far from Disney and I would want the most bang for my buck. I am not trying to be biased ,I just gave Universal all of our vacation money for the year, we were there onsite for a week instead of Disney. My older kids loved it, I would be disappointed to think I chose it over Disney if you don;t get to go frequently and you have a fourteen month old, there is much more to do/ride together as a family at Disney. Universal you sit at a playground and do baby swap pretty much.
