Okay, so I printed off a copy of Reviving Hollow Bastion from Kingdom Hearts 2 (The one hosted on Ichigo's). I played through parts of the song and it sounds just like the real thing, but I noticed that some parts seemed unplayable (In particular the segments starting at measures 10,24, and 30).

My hands are fairly large but I can still not make it all the way across some of those gaps. I have been playing piano for about 9 years now, and it still doesn't seem possible to play some of those parts, due to physical limitations of the human body.

Does anyone have any ideas/suggestions/tips for getting those measures to be playable and yet still sound somewhat accurate?

Take the notes down or up an octave? Or utilize the pedal and do all but one note of the chord, and then rush over to the far note.

Or arrange those measures, Or omit some parts, Or arpegiate them, Or see if you can use fingers of the the other hands.
