Because I am crazy when it comes to organization, I made this spreadsheet last year when I was planning to book. What I've deleted from this version is the section where my roommate and I both listed our top 12 choices for cabin categories side-by-side, then created a combined master list of what order we were going to try for categories in. It was color coded. I will spare you.
This spreadsheet lists only doubles because that's what I was trying for. As I recall, the triple and quad rates were about $50 less per person (so quads were $100 less per person than doubles). I also have a vague memory of these prices being around $50 higher in each category than they had been in 2011.
Since the ship next year is different (and newer), the categories are probably slightly off, but it's better than nothing, right?

Oh, and I just found this! Helpful to see how the prices differ based on occupancy:
