American Express Membership Rewards - Centurion Supplimentary Card Holders and MO

Is the one night free MO offer only available to the principal card holder or can supplimentary Cent holders book in their own right?

If I book two nights at a participating property and Mrs Oystercatcher books two more nights on her supplimentary, will we only pay for two nights?

The supplementary black card holder has this perk as well.

In theory, you could book 4 nights, 2 in the primary cardholder's name, 2 in the supplementary cardholder's name, back to back. And pay for only 2 nights.

yes and if you discus this more it will certainly be eliminated since CTS already says this perk is only available to primary card according to written internal documents. I disagree but let every post some questions so Amex elminates yet another perk.

A would guess that Amex's intention would be that it is available only once per account, particularly in the UK where the supp card is free with the account. However, this is an upside of Conceirge cluelessness. My advice would be to make each booking seperately and they probably won't work it our, although others on this forum have done both booking simultaneously.

Also, as I was recently informed by a Centurion representative, each Centurion card holder can book up to three rooms on this benefit.
So you can book a room for yourself + 2 rooms for your friends, and your supp card holder can do the same = 6 rooms on the 2-for-1 benefit. Good if you are a bunch of friends travelling together.

Source? I book back to back with my supplemental holder whenever I stay at MO. The concierges are familiar with the process, and have explicitly stated that it is a benefit for supplemental holders.
