Fresh water and a short summer. The season runs the same way as the beaches — cheapest in January in 4 of 5 — but milder: median swing 59% against the beaches' 73%.

Nightly lodging for a property sleeping four. The band spans the cheapest
and the most expensive of the 5 each month, so its width is the disagreement between
them.
The typical lake runs $235 a night across the year, against $295 for the library as a whole.
They are not one price. Door County, WI averages $197 a night and Lake Tahoe, CA/NV averages $304 — 1.5× the difference, for the same kind of trip.
As a group they are cheapest in January and most expensive in July, a 39% swing on the median.
Season matters far more at some than others: Traverse City, MI swings 75% between its cheapest and most expensive months while Door County, WI moves only 21%.
Every month of the year, this group is cheaper than the library median.
Per night is the average of twelve monthly rates for a property sleeping
four, so it is lower than a July quote and higher than a January one. A week for eight
adds lodging at the larger property size and the daily spend for eight people, and is
rounded because it is several estimates multiplied together.
