Main Street or right in front of the castle would be your best bet if you dont want to move. Just be prepared to stake out a spot at LEAST an hour in advance. Maybe even more. We like to watch Spectro over in Frontierland. It doenst fill up as fast and never seems as crowded. Then we are going to walk over by Dumbo and watch the fireworks from back there. Its great in front of the castle, but then you are stuck in the middle of a million people all trying to get out. We are going to watch Wishes behind the castle, and then take our time walking out and hopefully we wont be stuck in the masses.
