A floating week timeshare is assigned a specific range of week numbers, also know as a season, that the timeshare can be utilized throughout. Seasons can be denoted as Platinum, Gold, and Silver, or Red, White, and Blue or other designations, but are used to split the calendar year into sections based on desirability. Floating week owners will be able to book any week number in their season, as long as it is available.
A floating week timeshare affords owners some flexibility to book a grouping of different weeks of the year. This model allows the owner the security of buying into the season they travel during most, but provides some flexibility in the exact week number they need to travel during. Booking a specific week is subject to availability, and booking generally operates on a first-come first-served basis, but owning a floating week during the season you travel most, is a great way to strike a perfect balance between flexibility, and difficulty of reserving the time of the year you want due to low availability.
Floating week and fixed week timeshares are related in the sense that they are not Points-based ownerships, but fundamentally different reservations systems that offer different levels of flexibility and affordability.
