The staff was fine, if a bit hurried the day I went in. I can't remember the exact day but I'm pretty sure it was a weekday.
I'm not sure the wrap does exactly what it says it does, I think it just temporarily constricts the body tissue. It was definitely interesting, and it did work. They measured in several places, I forget how many, and I overall lost several inches! The process is strange, you are in there so tight you can barely think to move. I felt a little itchy with the product/solution stuff on...but she told me that meant it was working and I had no ill effects. I looked GREAT for my formal! And the dress fit just fine with absolutely none of that horrid "sucking in" to get it on.
