Oh no…a hand towel (or two) for a 3-night stay and a face towel would be nice for the same period of time, although I do happen to travel with an extra hand towel and my own washcloth but I’m not the norm.
For my guests, who have to stay a minimum of 4 ni., I provide 2 (3-pc sets) per person. The max is 2 persons…plus one extra 3-pc set. That is only because they have to use coin-operated laundry machines down the hall. If I had in-house machines, I would probably only provide guests with two sets ea.
PS: It is probably a “girl” thing to have two bath-size towels, but for equality, I give hubby and wife each two sets + the extra they can fight over.
