I go to three or more retreats a year. I gave up the prepare your own food ones. I want meals prepared, no clean up. I also want the option of a private room if no friend is going to room with. A weekend retreat close to home Friday - Sunday with three meals a day plus snacks, 24 hour drink station, nice room for two nights cost me about $350. Check out Roberts Carriage House Retreats. My group goes there once a year for a week. They have the perfect retreat house set up.
