I am relatively certain when taking a client on a tour of the Waterford, that they gave that information. Quickest way is to do that, either call and ask and/or go on a tour. They are most gracious and no pressure. It's a lovely place. It is of course the older end of Rossmoor, in other words not so many 55 year olds in Waterford.
I have many clients that live in Rossmoor and they LOVE it, from the single man who wants all his meals without having to cook, he would like Waterford, but others love the coops and some the home, know what I mean, depends on how much structured activity you want or like? They have it all. Good luck to you
