A timeshare combination is when an existing owner purchases another timeshare and combines it with their existing ownership.
Some clubs offer lower maintenance fees when ownerships are combined together, further motivating owners to consolidate their timeshares into one account. Combination can only be accomplished if both ownerships are held with the same developer, of course.
Specifically when you need to know how to combine WorldMark timeshares, an owner can choose to combine their existing ownership with another account. Generally, this take place as the result of an upgrading their ownership, where the buyer is seeking more vacation time and wants one maintenance fee and one owner number. There is a maintenance fee benefit to combining ownerships, as WorldMark’s maintenance structure uses a tier-based system to calculate maintenance liability.
