It has been enough for us so far, but if I had to do it over again, I would have went bigger on the end where the steps are located. If we ever do much entertaining, it may get a bit crowded.
The lounge chairs take up quite a bit of room.
We do plan to add on later this year or early next year with a cabana (or gazebo or whatever, and will most likely remove part of the fence and go a little larger. Obviously we will be pouring a pad for the cabana, so it will be a good time to add on.
Thanks
