I am interested in finding out how it works when one visits the Jacksonville location for the first time. Will I know ahead of time how long I need stay. I am about 3 hrs away and need someone to drive me and a dogsitter. This is a big ball of wax for me and preliminary planning is making me anxious. I also would like to know how I can find out what my out of pocket would be (roughly). I have Medicare but no supplemental ins and before I proceed need to know if I can afford it. thank you.
