Yes, I was looking through my album and realized that for my most recent trip, most of my character shots were outdoors. And yes, character spot has big windows bringing in natural light. I agree that the other locations you mentioned are much more challenging. And an external flash can be helpful. So it depends on your priority -- to me, you can still get away without any flash. And I wouldn't want to lug around an external flash for 2 or 3 pictures where it might be useful in the day. But, otoh, if you really want to capture the best possible shot with Mickey at the Town Square theater, then maybe carrying a flash is worthwhile. As to outdoor fill flashes -- for those purposes, I'm actually ok with the pop up flash.
