I love the idea of a banquet. I would have never thought of that! When I worked at a nursing home the residents did not have the arm strength to do bowling like you described, but we did table bowling and they loved it. We would play 5 rounds and then double whatever their score was so it would compare with real bowling. At the end we would give away 4 bowling trophies (which were donated) and they would get to keep the trophy in their room for a week. The next week when we did bowling again, we would round up the trophies before the program started and do it all over again. Residents loved it.
