^ 24.The preference for lighting in one’s hotel room is recorded in SA 677:1. While Rema maintains that it is generally preferable to light where one eats, in this case the hotel room is much more of a personal space than the dining room, as explained above in n. 21. Nevertheless, some maintain that the dining room is the preferred option.
For those lighting in the dining room, it would seem that even for those who follow Sephardic custom, each family should light separately, as the families are not sharing their food with one another. According to Pri Ĥadash, the families may not join together in the same lighting. This opinion notwithstanding, it would seem that if they do join together in the same lighting, they fulfill their obligation, in accordance with Levush (see BHL 677:1, s.v. "imo").
