Our DS2 & DD2 loved the 3D Philharmagic. That was our first 3D attraction. We rented a movie at home that came with 3D glasses so they could get used to the idea of keeping them on.
Although he loved Philharmagic, DS2 hated all the other 3D shows. We just had him keep the glasses off and DH took him out if he got loud. DD2 loved most of the 3D shows, although I covered her eyes a couple times! They all loved them for TSM. All kids are different!
I might suggest that you consider skipping "Honey I shrunk the Audience" show as both my little ones were scared, and big brother, who is 9, had a nightmare that night about snakes!
