There are tons of good courses. What area in KC will you be in? That would help to point you in which are good that are close. If your in south overland park I don't want to recommend courses up in the northland when good ones are a lot closer.
Tiffany greens is a good course and would be 10-15 mins away, the senior PGA tournament was there quite a few times. Loch Loyld is good as well but would be farther away from you more like 25-30 mins. Those would be my top two recommendations wth Deer creek coming in third. Its in south OP and would be 30 mins away atleast.
