Kingdom Hearts DDD Grinding?

[Arjahn]

Not sure if this should go here or in the gaming section, but I'm asking for some help, so for now I'll put it here.

If anybody else has Kingdom Hearts D.D.D. (or KH3D), do you know of any good places to grind at the early 30's? I keep getting my ass handed to me at the World that Never Was and can't seem to find a good spot to level up at, and Google hasn't been much help on this one.
