Singles and OAT/GCT

The single supplement now will be waived or offered at 50% off on all land trips and some river cruises of Overseas Adventure Travel (Cambridge, MA; 800/493-6824, www.oattravel.com) and its sister company, Grand Circle Travel (Boston, MA; 800/959-0405, www.gct.com).

There also are two new services to assist single travelers: 1) a free roommate-matching service, with the single supplement waived if the company fails to find an appropriate match, and 2) a “Travel Companions” board on the GCT and OAT websites. Travelers can create a profile and search for potential travel partners. 

Also new this year — a 30-day risk-free guarantee allows travelers to cancel a trip for any reason within 30 days of making a reservation and receive a full refund.
