Timeshares generally utilize among the following three systems: A fixed week timeshare gives the purchaser the right to solely use the property for a specific week (or weeks) every year. While the benefit of this structure is that the buyer can plan an annual holiday at the very same time every year, the other side of the coin is that it might be extremely hard to change the set week to another period if needed.While it is more versatile than the set week system, the "floating week" may not be offered throughout the busiest times of the year and may need to be reserved well in advance to ensure availability. The points system uses points to represent timeshare ownership, based on factors such as resort location, size of the trip home, and time of schedule.
