Fixed Unit: A time period that is fixed for each calendar year, either by date or by calendar weeks; most in numerical sequence 1-52. With a week number, your actual start date may vary slightly from year to year. Unlike a floating unit, a interval owner who owns a fixed unit at a resort will always vacation in the same physical unit each year he/she vacations at that resort. This type of ownership is particularly important if you have purchased, for example, an oceanfront property with the ocean at your door step and are not willing to vacation in an ocean-view unit. A fixed unit property assures the owner that he/she will always have the exact location and the exact unit they have purchased.
