Main Street USA doesn't have any rides, unless you count the train, but it does have some good resturants and entertainment. You can also take a look around some of their shops.

Fantasyland is where you'll find Cinderella's Castle. But if you like the rides not the stores check out
Dumbo- little kids will love this one
The Many Adventures of Winnie the Pooh- great for any age, just beware of long long long lines. It has fastpass though, but ya better get there early so you don't get a time between 11:00pm and 12:00am.
Peter Pan's Flight- this is one of my favortes, you wait longer to go on it than the ride actually is, but I think it's worth it
And my favorite and yours, It's a Small World- listen to kids from all over the world sing along to the ride, this has been one of my favorites since the first time I came! Anyone would love it!
And don't forget to go on the Tea Cups while you're at it!

Adventureland is for those who seek, well, adventure! It has rides like
Jungle Cruise- It could be better, but it's a lot of fun and does has fastpass
One of the best rides in the whole park, Pirates of the Caribbean- this is one of my favorites, don't miss it...Yo ho, yo ho, a pirates life for me.....
it's not a ride, but you can't miss the happy sounds of Tropical Serenade- Wait a second! Now it's "The Enchanted Tiki Room Under New Management" They redid it, it's shorter :( and more up-t-date :)

Frontierland is for us older kids with rides like
Big Thounder Mountain- hold on to your hates as you take twist and turns on a run-a-way train. It's the "wildest ride in the wilderness" my mom doesn't like this ride, it's a little bumpy. I think it's a lot of fun, and I don't really like roller coasters.
And what about Splash Mountain?- One of the best! It's a log flume with a cute twist, just don't brase you're self too hard on the big drop, it'll through you back really hard, and trust me...that hurts. This has fastpass!
And you have to go on Tom Sawyer Island- Adventure for the whole family
and don't forget about those loveable singing bears at the Country Bear Jamboree- cute, it could get a little borring, a nice place to sit down and rest after all those rides.

At Liberty Square, be proud that you're an American There's really only two main attractions
The Hall of Presidents- Beware, you're kids will fall asleep, but I'm sure that you'll love it...my parents do.
And the one and only...Hounted Mansion- this is also one one my favorites, it's even fun waiting online, you get to read the tomb stones with funny saying like, "Here lies bungy Biff, the cord was longer than the cliff." Watch the dancing ghosts at the party, and maybe if you're lucky..one of the ghosts will come home with you..(he, he)

Tomorrowland is my favorite part of the Magic Kingdom with rides like...
Space Mountain- a futureustic roller coaster in the dark, not for younger children. This too has fastpass!
Indy Speedway- ever wanted to be a race car driver?
It used to be called the People Mover, now The TTT or Tomorrowland Transit Authority-take a tour of tomorrow land
Alien Encounter- I was too affraid to go on this, but I heared it not very scarry. Not recomended for very young children or older children that don't even like that alien from the Great Movie Ride
My favorite ride in all of disney world..one of them any way...The Carousel of Progress. I memorized the words to the song! The audience revolves around a stage see how man has progressed since passed years.
Buzz Lightyear's Space Ranger Spin- You shoot at the aliens as you travel in your little car. Two people shoot and one moves the car around. This needs fastpass, but unfortunatly, doesn't have it :( It's a very long wait, but it's very cool!
there are some other very good rides and shows, it would take me too long to name all of them.

Mickey's Playland- for very yound children, visit Mickey's house or see a really cool show!
