The AoA suite runs about $51/more per night than the ASMusic suite (at $249 vs $198 per night respectively during value season).
From what I've seen, AoA offers a far better pool, a better food court, inside corriders, far more Disney theming...I think the $51 per night more is probably justified, IMO.
Pricing out the LM standard rooms vs. a regular value standard room, and it's only about $15-$20 more per night...again, look at the amenities...
And, POP has always priced out to be more than the All-Stars by a little bit...and again, IMO, I would be willing to pay a little more to stay at Pop than All-Stars (though I've loved them all).
