So I've been inpatient and like Angelique said its focused on meds I got zero therapy outside of music and art for 1 hour a piece in a week. You will likely not want to be there unless you are a fan of daytime TV and want to spend $2000 a day to be locked someplace safe. I got there while actively psychotic I wanted to kill someone....wanting to hurt yourself or others lethally will likely get you involuntary but if you want to get out whenever just mention it to your pdoc or t and see if they can get you in voluntarily or visit a psych ER if you're in crisis.
However, I strongly encourage a vacation instead....cheaper and a lot more fun and relaxing....
