This would be my plan. If you are staying onsite then forget my plan because with front of the line priveleges, you won't need a plan. Arrive at the entrance gate at 8:30. The park usually opens 15-30 minutes early so forget arriving at 9:00 AM opening. Ride Hulk and then ride Spiderman .
After Spiderman walk through Toon Lagoon and pick up express passes for Dudley. Pick the latest return time that it offers you. Then keep walking through Toon Lagoon without riding anything.
Enter Jurassic Park and have two adults take the 3 and 6 year old on Pteranodon Flyers if the line isn't too long. The other adults can go on Jurassic Park River Adventure while they are on P. Flyers and child swap with the baby on JP River Adventure. Then the other adults should be off P. Flyers with the 3 and 6 year old. Those two adults can then go on JP River Adventure while the adults take the 3, 6, and 1 year old into Discovery Center.
Now on to Lost Continent. Ride Dueling Dragons and child swap for this. Then do Poseidon's Fury with the whole family, stop and visit with the Mystic Fountain. Time for lunch. You can eat at Mythos in Lost Continent if you want a nice sitdown meal. If you want to eat cheaper with fast food but great atmosphere, go eat at Oak Tree Tavern across from Dueling Dragons.
Now onto Suess Landing. Ride everything there with the kids, especially Cat in the Hat and Red Fish/Blue Fish. Skip "If I ran the Zoo." (you'll be back later for that.)
After Suess, go across the bridge back toward Hulk. Go through Marvel Super Hero Island. If Spiderman, doesn't have a wait, then ride it again, otherwise keep going until you enter Toon Lagoon. Use your express pass to ride Dudley while the 1 and 3 year old go to Me Ship Olive to play with any adult who didn't want to do Dudley. If all adults want to do Dudley, then just do child swap at Dudley. Next is Popeye's, you will get wet, soaking wet, when you ride it. Once again the little kids will be entertained at Me Ship Olive.
If you still have some time, re-ride your favorite rides as single riders while the other adults just go back to Suess with the kids. Let the kids play in "If I ran the Zoo" play area while the adults rest and dry off. Meet up with the rest of your party at "If I ran the Zoo."
