S.B.
It is quite an event and there is a special parade, special fireworks and activities in the park- my family has enjoyed it and we don't have little ones, but we enjoy watching the faces of the little ones! They also limit how many tickets they sell, so the park is not so packed with people. Your son won't need a ticket until he is 3 so you won't have to buy one for him. It would be expensive if you added this ticket to a day when you were also paying for regular park admission. If you don't go to the park until your special tickets allow you in (which is a little earlier than the "party" actually starts.) then it would definitely be worth it. Make sure you plan for the weather, it can get very cool or cold at night. Have a wonderful trip!
