Seven consecutive nights, for example check in on a Tuesday, check out the following Tuesday.
The weekly point rate is provided as a convenience. It is equal to five times the Sun-Thur nightly rate plus two times the Fri-Sat nightly rate.
ETA: If your stay crosses seasons the weekly rate does not apply. You would pay the applicable seasonal rate for the nights that fall in season 1, and the seasonal rate for the nights that fall in season 2.
