Harmony is a self-serving 12 step based program that just happens to be in a lovely setting. Don't expect to see a doctor before 10 days or have your medication plan explained to you without pressing the MD because the nurses are unlikely to know the plan, let alone the medications. There is preferential treatment if you are on the "good" list, but if you are an advocate for yourself, expect to get multiple roommates during your stay, a crappy cabin and attitude from the medical staff.
If you stay for more than two weeks, you will start to hear the same staff stories and do the same exercises in you have already done in different groups. It's not all bad, but becomes very redundant and turns into groundhogs day.
