Im a relatively new MR member who has about 7-8 nights coming up at Marriott properties for some work travel. This will all occur in October, but unfortunately the nights were paid w/ my coporate AMEX and thus no double pts. That said, Im a NWA WP member as well and am wondering if it makes sense to just earn miles and bulk up my NWA account or earn pts.
From starting from scratch, earninbg say 20K MR pts would take me a long time as these nights will get me about 8,000 pts...vs about 8,000 NW miles.

Does earning miles make the most sense? Can I earn MR pts and still get the standard 500 miles for "staying" at a partner hotel?

Curious what the xperts do here. If anything, I fly more than stay at hotels, so an airline reward would seem to be more valuable to me....
