There are three primary types of timeshare usage. Which one is best for you depends on just how much versatility you require and whether you 'd like the option to check out a different locale from time to time. When you own a fixed-week timeshare, you'll go to the location during the same designated week every year.It makes yearly trips easier to plan, because you know well ahead of time when you'll be going. However, if you need some flexibility in your schedule or want to change up your holiday dates from year to year, this may not be the very best alternative for you. A floating-week timeshare permits you to choose the week you want within a designated season.
