Demand is generally based on season, and different seasons and locations will, of course, garner different levels of demand. For example, timeshares in tropical locations with a pleasant year-round climate can boast high-demand, and therefore higher rates, throughout the year. However, timeshares in seasonal locations like Cape-Cod may have high-demand seasons during the summer, and low-demand seasons during the winter months. In areas with a rainy or hurricane season, these weeks will generally be of low demand and therefore lower cost.
Exchange companies and many timeshare management companies now use color-coded classifications to determine the Time Division, demand and desirability of a particular interval week. For more information, see "Season".
