After being a Platinum elite for 2 years I was downgraded to Gold Elite this year. Up on checking with the Mariott rewards customer service team, they have offered me a platinum challenge to meet 9 stays in 3 months. Now, I wanted to check if there are any restrictions in terms of brands that I would need to stay at. for ex if I stay at Renaissance or a Residence Inn would these stays be still eligible and counted towards the 9 stays?
Appreciate your responses!!
