We have a smallish backyard (big enough for a swingset though) and it is a godsend. If you are one of those energetic families who loves to pack up and go out and be social, you won't miss it. (That's not snarky - I have a friend with a huge yard who nonetheless brings her child to the park every day after work, rain or shine.) For someone like me, who is perennially short of time, being able to have the kids get some outdoor time without dragging them somewhere else (or even changing out of my sweats or whatever) is really important. At this age it's more important to me than a nice patio - I figure when the kids are older we'll relandscape the playset area into a nicer patio than we currently have. BTW we also use Mosquito Squad, and while I know they are very controversial (and have abused these message boards before) it really does help in terms of using the yard year-round.
