Q and A
LEAD:  Nuns' Tours of Rome
Nuns' Tours of Rome
Q. I have heard about a group of nuns who conduct tours of holy places in Rome. Can you tell me how to contact them? - L. R., Bronx, N.Y.
A. The Ladies of Bethany are Dutch Roman Catholic Nuns who offer travel services at Foyer Unitas, 30 Via Santa Maria Dell'Anima; telephone 6865951. They conduct tours of Rome and the Vatican and give lectures at the Foyer Unitas, and the subjects are not only religious. The sisters are also available at Foyer Unitas to give information about Rome to anyone who stops by. Generally they conduct walking tours every Tuesday and Thursday morning and two Saturday mornings a month and give one-hour slide lectures Monday and Friday evenings at 5:30 (visitors are welcome at 5 P.M. for tea). They also arrange for Wednesday morning audiences with the Pope. Tickets for audiences must be booked ahead; a preparatory talk is given Tuesday at 7 P.M. All the services are free.
The schedule of tours and talks for the next month is announced late the preceding month. The December program includes tours of the Jewish ghetto, Vatican City and the Roman Forum. Among lecture subjects are the Catacombs and '2,000 Years of Daily Life in Rome.'
Some tours require signing up ahead of time. Foyer Unitas is open from 9 A.M. to noon and 4:30 to 6:30 P.M. on weekdays; closed Saturday afternoon and Sunday.  Biking the Florida Keys
Q. My friend and I would like to spend our winter vacation biking the Florida Keys. Are you aware of bicycle routes linking the Keys? -C.M. T., Southampton, L.I.
A. There is only one route that links all the Keys, the two-lane U.S. 1. Car traffic is quite heavy, especially on weekends. Florida highway officials recommend that only experienced bicyclists make the trip and that they ride only from dawn until 10 A.M. About 70 percent of the route, including all the bridges, has four- to six-foot paved shoulders.
If you are starting on the mainland, you can bypass 29 miles of U.S. 1 by taking the Card Sound Road from Homestead to State Route 905 in Key Largo, connecting with U.S. 1. ALong about 15 miles of U.S. 1 in Key Largo there is a separate bike path.  Tickets to French Open
Q. How can we get tickets to the French Open? Are there any tours that include tickets? - G. M., Chatham, Mass.
A. Reservations are being accepted now for the French Open tennis tournament, to take place May 28 to June 10 in Roland Garros Stadium in Paris. To get tickets, request a reservation form from the Federation Francaise de Tennis Billetterie, 2 Avenue Gordon-Bennet, 75016 Paris, France (telephone 47.43.48.00). Payment, sent with the form, can be made by check in American dollars. Officials of the French Open advise applying as soon as possible, as tickets sell out quickly.

Q. We wish to fly to Reykjavik, Iceland, then travel by ship to the Faeroe Islands, Shetland Islands and Bergen, Norway. Where can we find information on passenger ships that follow that route? We prefer to travel in spring or autumn. - M.T.H., Lanoka Harbor, N.J.
A. To make the trip, you will have to leave from Seydisfjordur, on the east coast of Iceland, rather than Reykjavik, and you will have to wait until June. The Smyril Line runs a passenger ferry, the 940-berth Norrona, that leaves Seydisfjordur on Thursday and arrives at Bergen on Tuesday, June through August only. On the way, the ferry stops at Torshavn, Faero Islands; Hanstholm, Denmark; again at Torshaven (where the line is based); Lerwick, Shetland Islands, and Bergen. Passengers can stay a weekend in Torshavn for $120 additional, skipping the Hanstholm segment, and pick up the ferry on Monday. The cost of the ferry trip is $277 a person in a double berth for the first three weeks in June and $342 thereafter.
The line's representative in New York is EuroCruises, Post Office Box 30925, New York, N.Y. 10011; 800-688-3876, or 212-691-2099.
