Hubby and I have taken the Friday morning class. It is a 3 mile session and is for beginners. I had a friend who was a renter and she was able to attend with her ID, if that helps you.
All you need to bring is a face towel(cause you will sweat!) and maybe a bottle of water. (although water and disposable cups are available there)
Different level DVD's are played on other days. The instructors can help with info in that regard.
Happy Walking!
