I does not too much of a difference. The Villages West or East are both pretty much right in the center of everything. The Hill communities are the ones which are not in the center of the village a require a car ride or shuttle if you have young kids or older folks with you. I have Aspen Highlands which is the highest point of all the units to we need to take a shuttle or drive just to get down to the village.
When staying in Village building you have to ask what your condo faces. An example is the Oaks, a nice building right next to the resturants and other activities like the big pool but you face either roads or parking lots. That is pretty much true for all West locations. But my teenagers have always loved the units in the West Village because it is close to everything. The East Village requires only a few minutes more of walking but for the units facing the mountains or the Village Commons have nicer views.
So in short, both the West and the East Villages are right in the center of things, pools, returants, ice cream polar, store, kids camps etc.
