I would definitely do AK if he is into animals and dinosaurs. Agree with everything Oneanne posted above, and Kali River Rapids is fun on a hot day. You can look at the map to organize your day, and make what FPs you would like depending on what's available, and then keep checking to get better times/modify - things will pop up, especially day before and day of - I would definitely FP Safari or do it at opening(or both - it's never the same twice!), and could FP Kali RR and Primeval Whirl in Dinoland, which is a good small, carnival style ride - as Oneanne pointed out Dino ride is loud, dark, with dinos roaring in your face, so you will have to judge if your son would like it. You can check out the show schedule on the app to get an idea of when to plan those into your day - Lion King is definitely worth seeing - great music, dancing, and acrobats. We like to do a land at a time as much as possible for less crisscrossing the park - we usually do Africa first(after checking for Devine in the Oasis - very cool if you spot her!) with the Safari, the Trail, and the LK show( and late brft at Tusker House - great character meal if you are interested!) Then we head to Asia, then Dinoland, and of course now there is Pandora to see, which depends on FP time if you can get one! Navi River Journey would be nice for your son, but don't wait in a long line if no FP - not worth that! But you can explore the land which is cool if you like. Discovery Island Trails are neat since you get up close to the Tree of Life to see the animal carvings. And of course some unique meet & greets, like Russell and Dug, Pocohantas, and Timon!
