Woodcroft is a great place for you to look especially since a (very) quick stalkerish look at you revealed that your kids are past high school age. There is a busy-ness to the neighborhood -- always people walking the trails, the main roads have traffic on them all the time, there is usually a certain population that is somewhat transient, particularly in the condos and townhomes. A lot of young professionals in those areas.
But the homes have a mix of young families and more mature folks. As a complete aside, I have seen more Suzanne Somers exercise equipment and dvds in Woodcroft yardsales ... Not sure what that says about a neighborhood.
There are a variety of restaurants near Woodcroft -- some would require passing a busy road, others would be pretty simple to get to. Pulcinella's, Chubby's Tacos, City Beverage, Shiki Sushi, Ruby Tuesday's and quite a few other options. But the area is fairly large so it would depend for walking where you landed. But a fair amount of the year you'll see people driving -- 95 degree & humid summer weather or cold rain (like today) gets people in their cars. There are 5 grocery store options within a very few miles.
If you were looking there -- no reason not to look down Garrett too. Lots of mature homes, but less of a planned community feel. Woodlake and Hope Valley Farms are also close developments. Many of the homes on the side roads off Hope Valley are older and very private with big lots. Some pricy, some reasonable. The Rockwood neighborhood is closer to the interior but some very pleasant homes there -- as are the homes near Cornwallis Rd. Park. Really, a realtor could probably rattle off so many more places to look.
Some folks will give you the blanket advice to avoid all of east Durham ... but I have a friend who lives in a super pleasant neighborhood just a handful of minutes from RTP and Brier Creek in Raleigh-- but Durham prices.
