Nice/spacious house with big deck in secluded back yard. Nice to have the ability to do laundry. Gated community is nice and great to walk or bike around (would recommend bikes, could put under deck or lock to a tree) but we sadly did not bring ours. There are walking trails through wooded areas behind houses which will take you to the pool area. Only went to the pool at end of the day for 30 mins once but was fine. Just less people later. My kids enjoyed playing tennis and there is also a basketball court, just bring equipment to play, there are some older racquets at the house. Can walk or bike to marina/bay.
About 20 min drive to beach. Saw variety of wildlife walking near Angola Neck Nature preserve which is a 5 min car drive (but could bike there, partially stone road) and biking at Cape Helopen Park which is 20 mins but was very backed up to enter. Take advantage of borrowing bikes there for free up to 2 hours if you don't bring your own, but recommend arriving early or you'll have to wait. Also have an 18 hole frisbee/disc course at Cape Henlopen Park between the Bike Barn area and the beach area (across from the playground/picnic area) which could be fun.
We had rain half the week but there are some games and puzzles at the house if you don't bring your own and Midway at the movies/Atlantic theater is fairly close if it's a washout kind of day! Overall, really enjoyed the stay despite the weather and would stay again if in the area.
