I looked into using some points to stay at St. Regis in either Maldives or Bora Bora. First off, it makes no sense that you have to call SPG to find out how many points it costs to book these locations. Makes planning very hard.
That aside, I am getting quotes of 90,000 SPG points per night for an entry level room. That's 270,000 Marriott Rewards points per night. With one free night for a weeks stay - 1,620,000 MRP.
I have the points to do it, barely, but I can't justify this.
Hopefully this insulting part of Loyalty will be corrected when the two programs are combined.
