A week is seven consecutive nights. On the point charts, the weekly rate only applies if all nights are in the same season. If any nights cross seasons, use the nightly rates from the appropriate seasons to calculate the total for the 7 nights.
Also, the weekly rates on the points charts are just for convenience of calculation. There aren't any savings. When you add up the points for the 7 individual nights, they still equal the week's total.
