This group of people is approaching retirement age and many have disposable income. The problem is, what are they to spend their money on. There are all kinds of entertainment things for kids (theme parks, water parks, playgrounds, etc) and for young adults (clubs, bars, etc), but what are younger retirees supposed to do with their time and money?

If you can come up with recreational ideas for older adults, you can have a very profitable business. Some ideas can be boating clubs, bridge clubs, bingo halls, card tournament clubs, weekly dinner clubs, etc.

Your main goal will be to organize a situation for these people to have fun. It may involve setting up clubs, finding meeting places and advertising your services. You can charge a membership to be a part of your organization, much like a health club membership. Your organization could be something like "retirement fun club" and you can provide a monthly calendar of events to keep retirees busy and having fun.
