Welcome to the DIS, dindoit.
I have watched Fantasy in the Sky, the closing of the day fireworks at MK, from just in front of Liberty Tree Tavern. It is a great spot to see the fireworks being displayed just over The Hall of Presidents and Columbia Harbour House. Great view. Another good spot is from Toontown.
As for the Share a Dream Come True parade, same spot, right in front of one of the food carts, on the Rivers of America side.
For the fireworks, I have never seen a crowd, everyone jams into the Hub area in front of the Castle. As for the parade, I would stake a spot out maybe 30 minutes before the start.
Enjoy.
