I am traveling on a traded time share week of my parents (but I am listed as a registered user). Personally am Gold now and will be Platinum by the time we travel. Will my Marriott status get same perks even when using the family's mvc timeshare?
I gifted a Marriott room to my son in Moscow 2 years ago and they told him he was not entitled to my platinum premium perks including breakfast at the concierge lounge. I thought this was silly and would advise you to act like you are the platinum member. Or get your folks to loan you their rewards card during your stay.
