The status lasts for 12 months, and normally requires 5 stays in a year to earn but will be renewed after just 2 stays during a year under this offer.
Benefits include 6pm late checkout, a one-category room upgrade each stay, a suite upgrade certificate once per year, complimentary internet, welcome amenities, and a luggage tag.
