I don't envy you right now... Too much room sound is a pain to deal with.
EQ might soften it a little if there are particular nodes involved, but you're at the mercy of the tone of the mix also. :shock:
Compression will pump it all over the place. :?
Limiting might be a "slightly" better choice if the louder parts take over the room sound pretty well... :-?
Best of luck, though.
