I think that the big difference is the starting location. From FW to SSR is an upgrade. From AKL to SSR is not.
That being said, I'm not a fan of any of the mega-resorts where you practically need a bus to get to your room from the food court.

I think that's why the people who were moved to SSR from one of the values weren't crazy about the move. However, since the OP was already at a really spread out resort (FW) then it's not that much different I think.
Your idea about asking if the OP could do WLV instead was a good one...might work, and great if it does, but I doubt it. I suspect that they usually have tons of space at SSR, and they are looking to fill it...
