Our 19 month old son was captivated by the show. THe lights and characters made the event very exciting for all of us as we have not been to a live show for children before. The downside was the special affects sounds were very loud and scary to our son. Such as the "Booming noise" during one of the songs and initially the Popping sound of the streamers being shot into the air or the "Thunder from the Count scene." The volume over all we think could have been toned down a little bit.
Also during intermission, they bring out at least 50 balloons of elmo to purchase and then ask everyone to put them below their seat so everyone can see the rest of the show. My suggestion is to sell these balloons after the show to avoid any irritated customers.
