I have my Itinerary some what done. I need some input:
April 29- Arrive in Orlando around 2pm
Hang around the village, orientation, and possible Downtown Disney.
( Candy Land Game)
April 30- Islands of Adventure (arrive around 930 am)
If you can, I'd try to arrive earlier. We arrived about 1/2 hour before rope drop and when we asked, they let us in early. Those staying onsite at Universal hotels are allowed in an hour early so they can go directly to Potter. Lower crowds that way. They let us in, we walked past Seuss Landing and directly to Potter. We stayed for about 2 hours, walked through the castle, did the Hippogriff ride, our older son did the big ride and we wandered the shops. We asked at the exit to the owl post if we could enter (we showed the GAC card for Universal indicating it was a wish trip) and they let us enter... they may not, they're not supposed to let people in but really, Universal was phenominal with wish kids. even moreso than Disney. Its worth a shot to ask. The Potter area can get incredibly busy. Even though you'll be able to shortcut the rides, the area is packed. The earlier you are there, the better as far as crowds are concerned.
Breakfast at the Village 8 am
Seuss Landing
I'd do this after WWoHP
The Wizarding World of Harry Potter(around noon for lunch Three Broom
Sticks)
Marvel Super Hero Island (Matthew has to meet Superman it a must)
We didn't see Superman. I really don't think he's there. Our first day we saw Spiderman and Wolverine. Then our second day, the cast mermber for Spiderman saw us in the street with the lanyard and asked if we wanted to meet them all. They were all due to leave their spots at the same time. We went down a back alley and they all came to us for a private meet and greet. Great pics with all the superheros... but no superman. Just didn't want your' little guy to get too disappointed.
I have no clue what else because Matthew is 38 1/2 inches and they
have a lot of height requirements. Maybe 4 big rides for me and
my hubby. Suggestions
He shoudl be able to do the kids ride at HP. Sydney loved Seussland. My little guy was 39in at the time. He had a blast there but didn't really ride the rides. He enjoyed the museum area in the Jurassic Park. He loved Seussland. My two younger kids LOVED the frozen butterbeer in HP... it was actually the only reason we went back a second day... Sydney really wanted more butterbeer
Oh, we I should say, we spent from 830ish til 3pm at Islands of Adventure and then went to the Universal side. There we did the Barney show, the ET ride, Shrek movie and Jimmy Neutron ride. My oldest did a few other rides but Sydney and her brother were too short for many ... they just had fun meeting other characters like Scooby Doo, Diego, etc.
Dinner at the Village
May 1- Magic Kingdom (9am) (not in order)
Quick breakfast from the food cart at the Village
Dumbo is Matthews number one ride.
Buzz lightyear's space ranger (Meet Buzz and Woody)
The best place to meet them both at the same time is at HS. They're together for meet and greets there. In MK Buzz is on his own and Woody is with Jessie in Frontierland
Ride the Train around the park
Lunch around 11 counter service (Suggetions)
We like Columbia Harbour House in Liberty Square best. Pecos Bills is great for burgers in Frontierland too
Matthew has appointment with Pirates league and Emmy with BBB
Go with the flow after those have been acheived
I wanted to get on Big Thunder but its going to be down when we are
their. Other then that haunted Mansion and splash mountain.
Goofy's Barnstormer should be opened then. Its a great little coaster... I think height is either 36 or 38 so he should make it. Splash is 40in height limit. He'll love all rides in Fantasyland except maybe Snow White which is a little scary.
Meet a few princesses, a parade, and fire works
Dinner at Crystal Palace at 7pm
That's a really late dinner. They may be late seating so you wont' get seated til maybe 730, out by 830... that's cutting it really close for the parade. Can you get an earlier dinner??
May 2- Animal Kingdom (early as can be) and Hollywood Studios (4 pm)
Quick breakfast again or make an early breakfast
Do as much as possible before 4 pm at the Animal Kingdom
You can do almost everything there before then. We usually leave right after the parade, or before if we don't want to see the parade. At Lion King, ask if there is special seating. They sat us in a location wehre the performers asked Sydney to be a part of the show... it was nice... she didn't want to but her brothers had the opportunity as well and jumped at it
Having lunch at Rainforest Cafe at 12pm
Go to Hollywood Studios at 4 pm
Like 10 attractions we like to see
That's a lot to see there... and its hard because the shows are very time dependant ... you might not get it done if you wait until 4pm to go there...
Dinner at 50s Prime Time Cafe at 630pm
May 3- Not sure if going to Universal Studios or pay another day at Magic
Kingdom. It all depends if we seen everything we wanted the first
time. May be water park. Suggestions
The cost of one day at MK, depending on the size of your family, could be really high. While I think its great to have two days there, its definitely at a significant cost. We added several days to Sydney's trip so we could spend more time in the Disney parks. If you can do that, I'd say do it over a second universal day... just based on the age of your kiddos. Its really hard to see all of MK in one day and its by far the best for little ones.
(Winter Wonderland Festival)
May 4- Epcot (Not in no rush 930-10)
Have breakfast at village
All of Nemo
Not a lot there really. There's the Nemo ride, Crush show and the aquarium. It won't take that long.
Check out some of the world showcase
Lots of fun. Many princesses there that dd may like to visit. Good snacks there too. My kids really like the Serveur Amusant in France (basicallly an acrobatic chair juggling type show... although that's a terrible explanation 
Lunch some where in between
We like Morocco (chicken there for the kids), fish in England is also good
Dinner at Le Cellier at 630pm
Suggestions for what the children like at Epcot (toddlers)
Its actually my kids fav park next to MK. They can do the Kidcot stops which lets them get a 'charm' made of paper to add to a mask... they can colour at each stop... in each of the countries. My kids like the Journey into your imagination, the jumping fountains near the Journey into your imagination, they like Living with the Land, the ride in Mexico, the ride in Norway
May 5- Sea World (before departing home)
I don't know if our flight is early if it isn't possibly check out the aquarium.
Matthew and Emmy have been to two different aquarium so i don't know if they would be interested in another.
They do nice things for wish kids here. We spent 1/2 day here and then went to Universal for another 1/2 day. At Seaworld, let them know at the entrance/food areas of the feeding stations that its a wish trip. They provide free food and trays for feeding the dolphins, sea otters, and rays. They also let you in a little early to feed the dolphins so you get a chance before everyone else arrives. We didn't do much else there besides the dolphin show. Part of Sydney's wish was to see the dolphins so we focused on that aspect of Seaworld and then went to Universal so she could get another butterbeer
Thats it! I am going to try making it to some of the events at the Village but i am not making any promises. Please any suggestion would appreciated.
