Mention the fact that you're a senior when you make your travel reservations. Many hotels offer discounts for seniors. In most cities, people over the age of 60 qualify for reduced admission to theaters, museums, and other attractions, as well as discounted fares on public transportation.

AARP offers members a wide range of benefits, including AARP The Magazine and a monthly newsletter. Anyone can join at the age of 50.
