Eliza,
Yes, you should buy a Child's
park ticket for your son who is 5 years old. Adult tickets are for those that are 10 years old and older, and a child's ticket is for those kids aged 3 to 9.
I would also recommend that if you are coming down with a 5-year old that you explore some of the great resources on the website that help you find the right activities for you and your son. I particularly loved using the
Planning for Preschool Kids & Little Ones page. It helped us zone in on what attractions might be best for our girls, and also helped us find those that we would enjoy alongside them. Knowing now what I did not know then, it helped me avoid rides that might have scared them, and helped us find experiences that really made the trip special for the whole family!
Write us back with more questions, and we can help you plan further!
Have a Magical Vacation!
