I've stayed at the villas a lot. So many people complain about the "long walk" to the elevators, but I've stayed at other Disney resorts that had walks that felt much longer (YC, BC, AKL come to mind right away). I also don't feel that the restaurants are any farther from the villas than from the inn - that all depends on your room location. I have been on the top floor, ground floor, and every floor in between, and never felt that the walk was bad.
It really depends on the number of people in the room and whether the larger fridge and the microwave are a benefit to you. If there are two adults willing to share the bed, or if they have small children, then the villa is a good fit. If you have more than two adults, or the two adults don't want to share, then you might prefer the two regular beds in the inn.
