We saw the Christmas version of this and it was a great way to end the day. The usual high standards of Disney production are in full force here. Projection, lighting, pyro and fountains all beautifully choreographed together for a fantastic show. We watched from a quarter of the way up main street and be warned that parents will put their kids on their shoulders as soon as it starts blocking everyone else's view. When we watched we even witnessed a crazed mother dragging a bin from outside a shop into the middle of the crowd for her kid to stand on.
Definitely stick around for this though as everyone in the family will love it!
