If you have a golf cart, my personal request is always 'back of loop'. That gives you a cabin farthest from the road and bus stops. Outside of loop is also a preference - as the inside ones sometimes have too much of a view of other cabins - though depending on which loop you're in, some of the outside loops can back up close to the next loop's cabins - that's why I really prefer the outer cabins at the very back of the loop, which usually have just woods or canal behind. Feels more 'woodsy'. For those without a cart, it means more walking to get to the bus stops - not that it's a great distance, but something to keep in mind.
I always liked 2800 loop, and 2700 loop (except the cabins 2738 and higher) - because it's big, had almost all woods behind in all directions, and is far from the pool (I don't use the pool when I go). If you intend to use the pool a lot, then you'll want the lower loops like 2300, 2500. In 2700 loop, 2738 and up back up to the pool area, so I avoid those again because I like the woodsy views.
