You can HEAR the fireworks but given the way the land lies (pretty flat and low), and the fact that you will want a south facing pool and the park is not south, you will most likely not see them. I think if we went to an upstairs bedroom and looked out you could see the higher ones. If you go to the main road (Old Lake Wilson Road) you can see the high ones and you can even see the tree of life (Animal Kingdom is the closest park). You are VERY close to the parks!
You will need to learn how to use Sherbeth road - Sherbeth takes you right into Disney without using 192 which can be very busy. We used it ever day and you can access it from Old Lake Wilson, to Funnie Steed to Sherbeth.
