When we were there in March we saw two different groups. They came out of the space between UK and Canada marched towards the front of the park and stopped to perform right in front of the big fountain (on the side closer to WS) then marched towards Test Track. What we saw was most of the families staying by the fountain waiting for the group to come since that is were they did their big number, this way you would get Spaceship Earth right in the back of them if you angled the picture right
Wish your daughter good luck!!!
