Many museums and attractions in Eastern Europe offer free or reduced rates to people of retirement age. However, few hotels offer age-based discounts and no restaurants offer the early-bird specials so popular with the over-50 set in the U.S. However, members of AARP (formerly known as the American Association of Retired Persons), 601 E St. NW, Washington, DC 20049 (tel. 888/687-2277; www.aarp.org), may get discounts on hotels, airfares, and car rentals if these are linked to a U.S.-based company. AARP offers members a wide range of benefits, including AARP The Magazine and a monthly newsletter. Anyone over 50 can join.

Many reliable agencies and organizations target the 50-plus market. Elderhostel (tel. 877/426-8056; www.elderhostel.org) arranges study programs for those aged 55 and over. ElderTreks (tel. 800/741-7956; www.eldertreks.com) offers small-group tours to off-the-beaten-path or adventure-travel locations, restricted to travelers 50 and older. Recommended publications offering travel resources and discounts for seniors include: the quarterly magazine Travel 50 & Beyond (www.travel50andbeyond.com); Travel Unlimited: Uncommon Adventures for the Mature Traveler (Avalon); 101 Tips for Mature Travelers, available from Grand Circle Travel (tel. 800/221-2610 or 617/350-7500; www.gct.com); and Unbelievably Good Deals and Great Adventures That You Absolutely Can't Get Unless You're Over 50 (McGraw-Hill), by Joann Rattner Heilman.
