I asked the same thing last year, but my dd was only 2 1/2. I was told to consider how she would be sitting in church for that long. Well, fo her sometimes, she'd sit quietly, and others not so much. We got tickets with the CP package since it was on dining plan anyhow, and it ended up raining that night. We did go back to Epcot another night, and we watched some of the concert while we were waiting for Illuminations. I hadn't realized that you can see in even if you are not sitting in there, so you can get a taste of it without actually being in the theater. It was beautiful, but not so wonderful that I was disappointed about getting rained out with a 2 1/2 year old. A 4 year old might like it.
