One of the things I dislike about WDW is their location of lockers. I suppose it makes sense in that you drop stuff off just as you enter and then pick it up as you leave but, to me at least, a set of lockers in a more centralized location makes FAR more sense. Then, throughout the day, I can visit the locker to drop off/pick up things like a camera, water bottles, etc. With the lockers being up front you have to make the trek all the way to the front of the park to swap anything out and at the Disney parks, with the way they're laid out, it's pretty inconvenient.
Some non-Disney parks get this and put lockers throughout their park (Six Flags comes to mind) so if you want a central location, then you have it. If you want something up front, then they have that, too.
