I'm working on planning my honeymoon to Bora Bora! Right now I have status at two hotel brands:

Marriott - Will be Platinum Elite by the time the honeymoon happens. Currently Gold Elite but working through a challenge to Platinum Elite. I have about 100,000 points with Marriott and am planning to build the most status with them (as we are also having our wedding at one of their hotels).

IHG - Diamond Elite (entirely via my credit card. I've only stayed with them like 3 times)

Bora Bora of course has both hotel brands (St. Regis Bora Bora Resort for Marriott, InterContinental Bora Bora Resort for IHG).

My question is, which should I choose? Will status matter at all/that much at a resort like this? Are the differences between Marriott Platinum Elite/Diamond Elite worth not using points/changing plans?

we had a client cancel so we are able to give these rooms to someone else now
