I always liked POR because of the theming and the trundle in AB. However, I think I would now lean toward CSR - which we also liked - because of the rehab and the queen beds.
I used to despise ASMU until we were "stuck" staying there Christmas 2007. I fell in love with the refurbished rooms and we've stayed there since. We actually stayed there last week and have to say our room still looked new and was sparkling clean. I've read the ASSP is simlarly refurbished, too, so I'd consider that, but I love, love, love ASMU.
