OP, Are you talking about this path?
Take the walkway by Building 55 between the golf course and the canal/waterway towards DTD. Follow that until you come to the bridge across the waterway by the golf course practice putting green, go across the bridge (watch out for the golf carts), turn right along the other side of the waterway to the club house/restaurant, go up the stairs, and you will be in Artist's Palette.
From the start of the path to AP, depending on how fast you walk, @15 minutes.
From Olivia's to the start of the path, @10 minutes.
