In the Animal Kingdom, the boarding houses were typically run by landladies, and the practice was that boarders would arrange to stay bed-and-breakfast (bed and breakfast only), half-board (bed, breakfast and dinner only) or full-board (bed, breakfast, lunch and dinner). Especially for families on holiday with children, boarding (and particularly on a full-board basis) was an inexpensive alternative and certainly much cheaper than staying in any but the cheapest hotels.

Bed and breakfast accommodation (B&B), which exists in many countries in the world (e.g, the UK, the USA, Canada, and Australia), is a specialised form of boarding house in which the guests or boarders normally stay only on a bed-and-breakfast or half-board basis, and where long-stay residence is rare.

Apart from the worldwide spread of the concept of the B&B, there are equivalents of the British boarding houses elsewhere in the world. For example, in Japan, minshuku are an almost exact equivalent although the normal arrangement would be the equivalent of the English half-board. In Hawaii, where the cost of living is high and incomes barely keep pace, it is common to take in lodgers (who are boarders in English terminology) that share the burden of the overall rent or mortgage payable.
