Actually, my calculation was wrong, I realized now.

The MR is:
a) 12 x 60 € = 940 $ = Diamond incl 4 suite upgrades + 30,000 points
b) 16 x 60 € = 1,250 $ = Diamond incl 4 suite + 50,000 points

Not such a great deal in my opinion but it would save me lots of time and travelling because I could do it in two check-ins and done.

Background: I have a fast track, 12 nights within 60 days, valid until end of July.

The problem: right now is the weak promotion which gives me 44k points for 16 nights. Maybe there is a better promotion in May, maybe there is nothing. However, it is not sure that I will be able to find 60 € rates in summer near my town.
