Just make sure you give him some time in Camp Jurassic. Although, there is a chance you may not see him for the rest of the vacation

When our kids were your child's age, we would have to budget at least an hour or two for both Camp Jurassic in IOA and Curious George in Universal.
Camp Jurassic is a wonderful playground with rope bridges, hideouts and waterguns. Oh yeah, make sure he is in clothes that can get wet.
Another non-ride, 6 year old special is bring a roll of quarters to put in the water guns at Popeye. Nothing more fun for a young boy than to shoot water cannons at the people who might have escaped getting totally soaked on the Popeye ride. Make it his mission to not allow anybody to get off Popeye dry
It is all a 6 year old needs to keep him busy for hours at a time!
