How do you feel about her staying in a hotel with you? I was really glad not to share a hotel room with anyone during family week with my husband's first rehab. Too much of my own emotions going on and I was wiped out. I needed me time. Being in the same hotel as my husband's family (if they would have known and went) would have been too much.
Did she go to rehab herself? Whether she did or not (and stepping back to look at this without my own emotions) this may be good for her and her relationship with her brother. Counselors are usually pretty good at working with anyone, regardless of what gets them there. Learning how to hide usage is not on the formal agenda. If she wants that, she can find addicts anywhere with that problem and it always comes out somewhere. What will likely be covered is the importance of working our own programs and staying sober/clean no matter what.
