I recently reached out to MR, with the question, "what are the
additional benefits of PP above regular P" - this was their reply (sent by a Team Leader")
"With Platinum Premier status we would honour the top 3% of all our Platinum members in terms of overall revenue and stay nights, so this is quite an achievement for you. Whilst there are no further benefits on paper for this new status, it does give our hotels the opportunity specifically recognise our top members. Furthermore, we you may contact our dedicated Platinum Premier desk on email
[email protected] for any assistance with hotel reservations, coordinating partner rewards or assistance with your Rewards account."
Hope this lends some insight
