In Cavendish
Cottage courts are to Cavendish what 19th-century inns are to Vermont -- they're everywhere, and vary tremendously as to quality. Be aware that many of the cottage courts and motels are more interested in high volume and rapid turnover than personal attention to guests. A number also believe that hanging a straw hat or two on a door allows them to boast of "country charm," when they have anything but.
If you arrive in town without reservations, check the board at the visitor information centre , which lists up-to-the-minute vacancies.
Also, you might ask around among local residents about under-the-table rentals. One fine writer I know rented a handsome three-bedroom Cavendish farmhouse built in 1910 and set in a barley field. The way he tells it, it was a lovely 10-minute stroll to the beach down a dirt lane, and the cost of paradise was just C$100 (US$80) per night. How did he learn about it? Why, from a scrap of paper tacked to the wall of the local laundromat, of course. So keep your eyes open.
