Platinum Premier

For members who remain in the top tier of Platinum, for multiple years consecutively, Platinum Premier is assigned. There is no actual given threshold, such as "stay over 120 nights per year", but Premier members are assigned based on an internal, unpublished, formula. There are no additional described benefits over Platinum except members are flagged as VIP on check-in and given "additional consideration" by hotel management and staff during their stay. There is also a dedicated Platinum Premier number available to these members. Renewal of Platinum Premier status requires a minimum of 75 nights stay.
