Q. A woman that usually lights many (Shabbos) candles (at home), when she travels, does she have to light all of them or only the basic two?
A. Horav Shlomo Miller's Shlit"a opinion is that today most women when they travel or visit, only light the customary minimum of two candles. This implies that any particular woman, when she begins to light candles assumes this established majority tradition, and needs to light no more than two. (See; Tamtzis Halochos 263,20 and Vehoish Mordechai 3,2 for a similar response)
