If you are members robes and house shoes are in your room. If not, I don't believe they will be in your room, but you can request them, I feel certain.
We have always had robes, both Desires, before and after we got a membership. At a certain point, everyone is walking to and from the hot tub in robes. I can't imagine they would limit who gets a robe.
We are not members, and we haven't had robes in our room the last 3 or 4 visits. We did get them when we called and asked for them, but last trip we didn't even ask.
