Rather than a vacation condo with pool and golf course, I would like to rent a place for several weeks in Los Angeles and New York City. Do you know of any Web sites for city condos or apartments? - Ruth E. Kahn, Detroit
Sublet.com , (877) 367-7368, offers a range of rentals worldwide, posting thousands of listings each week and updating them daily. Once you click on the area you're interested in and find the listing you like, you register, for a fee, and are then provided with the phone and e-mail address of the property's owner. For a 90-day search in Manhattan, the fee is $75; in Los Angeles, $39.95.
I am interested in educational tours such as those offered by university alumni associations and led by professors. Is there anything like a central listing of such programs? - Lily O'Connor, Edina, Minn.
Academic Arrangements Abroad has since the late 70's designed educational travel programs for museums, cultural organizations and alumni associations, including Princeton, Dartmouth and the Metropolitan Museum. Its Web site lists tours by destination (Europe, the Caribbean etc.), by interest (art and architecture, ancient civilizations, etc.) or by date. On July 12 to 24, the Metropolitan Museum and Phillips Exeter Academy are sponsoring Byzantium's Northern Shore: The Black Sea aboard the Sea Cloud, with Helen Evans, a curator at the museum, and Richard Murphy, former ambassador to Saudi Arabia. From $7,950, double occupancy (without air fare); (800) 221-1944; http://www.arrangementsabroad.com/ .
Academic Travel Abroad has been designing tours for more than 50 years.
