I think everything will be great just hold on to him if you're going into the balcony it's steep.
Just saw Christmas Carrol in a box. It was a fun seat. There are two seats in a box, my wife sat near the edge and I could could look over her. Two kids would have to share the edge seat. Lots of kids had great views in the first row of the balcony. I'd say that's my recomendation. But the balcony is steep so maybe they'd be good anywhere up there.
Unless you get a front row balcony. Should be good.
This theater has great seats no matter where you chose. However no matter where you seat a 2 years old will struggle and will have to stand.
They may have to stand in order to see well especially at the front of the box due to half wall.
