-Bring a small tub of play doh and let him play with that. You could even challenge him to construct certain Disney characters.
-Bring a few pipe cleaners and again, let him create different shapes or characters.
-Games like I Spy, 20 questions, thumb wars, or rock, paper, scissors
-Discuss what rides or shows you'd like to do next, or what he has thought about various activities so far.
-Ask him Disney trivia questions.
-Look for hidden Mickeys.
-Bring a small toy or action figure that he can play with.
-Snacks.
-Depending on where he is at with math and reading, you could maybe ask him simple math problems like 1+2 or how to spell simple words by sounding them out, like "bat" or "me." My DD loved doing that at that age.
-Go back and forth telling a story, switching after either every word or every sentence and see what kind of crazy story you guys come up with.
-If he has shoes with laces, practice tying shoes.
-Flashcards with math, words, trivia, etc
Sticker book or sticker puzzle (as long as he knows not to put them all over the queue, etc)
-Small coloring book or notepad. A DVD case works great for holding a few crayons, stickers, pieces of paper, etc as well as provides a hard surface for coloring.
-Practice rhyming
-Disney Alphabet game- go through the letters and come up with a character, movie, ride, or show that starts with each letter
-Bring an "I Spy Bottle." Make this at home with a plastic bottle (a clean, clear soda bottle with the label removed works great). Find some small random objects (like a shell, marble, bead, button, paperclip, sequin, plastic gem,
Lego, mini toys, just to give a few ideas) and put them in the bottle and fill it up most of the way with rice or sand. Tighten the lid really tight or seal with hot glue for an extra hold. Tie a ribbon with a piece of paper listing the items around the lid. Shake it up and they have a portable I Spy Bottle to play with in lines.
