The unique quartershare (13 weeks) interest in the Marriott Grand Residence Club allows you to take full advantage of vacation home ownership with the flexibility to trade for other properties worldwide. The thirteen week fractional ownership interests are classified as Quarters 1, 2, 3, or 4, but they do not match up with the classical calendar quarters. The owner of a quartershare is entitled to a usage week every 28 days, with Christmas and New Year’s weeks consecutive every fourth year. Weeks may be used, rented, traded with other Grand Residence Club owners, or exchanged through Interval International as a five star exchange.
