No, the Accor Plus membership is strictly for the person whose name is on the membership card and is non-transferrable.
Have you thought about getting a supplementary card? A supplementary membership entitles the cardholder a person access to all the member accommodation and dining benefits except that it does not include Stay Plus complimentary night, local discount vouchers and it must be attached to a primary membership.
Alternatively you could request a Member for a Day certificate. A Member For a Day certificate enables a current member to invite a non-member to enjoy the Accor Plus dining and accommodation benefits for a 24 hour period (excluding the use of the Stay Plus night, as this can only be used by the member).
