EDIT: The ToC are actually pretty clear. If you achieve globalist by hitting 60 nights or 100k base pts, you can requalify the following year with 55 nights or 100k base pts.
(a) Requirements To Earn Globalist Status: Members who, in the course of one (1) Calendar Year, record a minimum of sixty (60) Tier-Qualifying Nights or earn one hundred thousand (100,000) Base Points will receive Globalist status after meeting the minimum requirement through February of the second Calendar Year following qualification. Please allow approximately seven (7) business days from the checkout date of the stay during which you qualify for a new elite status to be applied to your membership. A member who, after March 1, 2017, who qualifies for Globalist status by satisfying the minimum Tier-Qualifying Night or Base Point accrual standards set forth above may re-qualify for Globalist status for the following year by either recording a minimum of fifty-five (55) Tier-Qualifying Nights or by earning one hundred thousand (100,000) Base Points during the current Calendar Year.
