Getting the staff and visitors involved is of paramount importance. At several locations I would have one of the young staff ladies kick off while I played and sang YMCA, then I had some of them do some high kick (Rocketts) line dance while I played and sang NY - NY. Many of the retirement communities I performed at also had ballroom dancing classes and line dance classes, so it's a goood idea to brush up on those tunes as well. Most of all, be an entertainer - good entertainers are hard to come by, while good musicians are a dime a dozen in my part of the world.
Good luck,
Gary
