We went when DS was just over 2.5 and he loved it, especially the MK and Epcot. I am now desperately trying to find a time to go again (he just turned 3) while he's in this "everything is amazing" phase.
I will say that our time there was best when we were able to focus on DS and follow his schedule/moods/interests. When we tried to coordinate with the rest of the family on the trip, it was a lot more stressful.
When in April? Check out the crowd calendars at easywdw.com. If you can go to the MK during a recommended day (usually Tuesday and Wednesday are best) and not during a peak period, you'll have a lot more fun.

definitely worth it. Took our 3 and 5 year olds to the Magic Kingdom last spring and they were in heaven. There are a lot of rides he can go on - most of them, actually, except for the few big roller coasters like Space Mountain and log ride. We went from noon until the fireworks show and did Dumbo, flying carpet, teacups, carousel, Goofy's mini-coaster, the train, the racecars, jungle cruise as well as an early character dinner around 4:30. The Pirates of the Caribbean was the only one my 3 year old didn't like, it is kind of scary with thunder and lightning, ghosts, skeletons and cobwebs etc. We didn't even get to Tom Sawyer's Island and the new Beauty and the Beast village is now open (p.s. you can get BEER, unheard of until now, if you book a meal for the 'Be Our Guest' dinner show.)

At 37 inches, there will be 4 rides a child can not ride in Magic Kingdom at Disney World

Splash Mountain
Space Mountain
Big Thunder Mountain RailRoad
Stitches Great Escape (not really a "ride" but there experiences that if you not a certain size, won't work)

Everything else (which is a LOT), a 37 in child will be able to ride...and if the child has a sudden growth spurt and is 40 inches by the time you go, they will be able to do EVERYTHING except Space mountain (must be 44 inches for that)

Legoland, there is actually 5 rides a 37 in. child can not ride:
Flying School
Kid Power Towers
Aquazone Wave racers
Test Track
The Dragon

Everything else (which is a lot) he will be able to ride. However, for A LOT of those, he will have to ride with an adult--as in a 1:1 ratio. So if a parent was to go alone with her 37 inch child and his 40 inch sibling, there would be an additional 8 rides (+ the 5 they can't ride at all, as they are too short) they will not be able to ride--unless the parent has each child wait by themselves off to the side...not something I would be comfortable letting a 3 year old do.

Pp here that you quoted above. I have been to both Legoland CA and FL as well as Disneyworld and Disneyland. There is way more to do at Magic kingdom for younger kids than Legoland. I think for the money Disney is a much better value and experience for younger kids. We love Legoland but I just think it is better for the 6 - 12 range.

Anonymous wrote:Legoland is not good for younger kids as they have stricter height restrictions on rides than Disneyworld. Your three year old would not be able to ride many of the rides. Disneyworld would be fine for a three year old. I suggest going to touringplans.com. They have strategies for getting through the park with younger kids. I used their app this past fall when I took my 4 and 6 year old and we had a great time.

Really? We took our 3 y/o to Legoland last summer and I think there were only 2 rides he wasn't tall enough to go on. He absolutely loved it. I've always heard the reverse- Legoland is better for younger children, Disney is better for older.
