How do you calculate this for a Plat or Gold?

1 dollar earns 2 points for regular member

Plats and Gold earn 3 points.

Does the double points option multiply based on 1 dollar = 2 points or 1 dollar =3 points?


I suspect it's the earlier one... 1 dollar = 2 points and with double point promo, it's 1 dollar = 4 points. And Plats and Golds earn 5 points per dollar?

Let me do the math...

In October, I have a four night stay @ LM Etoile with a rateof 199 Euro per night.


Assume 200 EURO = 300 USD.

For this stay, per night, I would normally earn, 300 x 3 = 900 points, and with the promotion, I would gain additional 600 points per night. That's about 2400additional points for this stay.

I guess the benefit is that if one stays at a higher rate, expensive hotel, earning potential is great... but for me, 300 USD per night is just about the highest I will get for my work related travel and even for vacation.

So, I would probably earn less than 10000 additional SPG points through this double points options... that's a no go for me... for now.
