It varies, so that's a hard one to predict. One option might be to get a FastPass for the parade, in which case you get the view you're wanting. We have done that once, and while I hated "wasting" a FP on the parade, it was actually quite nice. We were able sit on the sidewalk, front-and-center. Being so relaxed, our younger daughter actually fell asleep, which prompted two entertaining results: (1) Dopey saw her from his little train and pointed at her and put his hands to the side of his head, as if he was asleep; and (2) Cinderella's stepsisters saw her and started yelling at her to wake up - ha!
Thinking more about the FP option, it did seem like that whole little in the center of the hub was roped-off, so if that's the precise view you'd like to have, a FP might actually be necessary. We have not seen the MSEP since they have opened up all the new "garden" areas around the hub, so I'm not sure how (or if) that might affect the enjoyment of the parade....guessing it's better for fireworks than the parade.
