Sefan-
How come no miles at fairfield. Under the Marriott Rewards Program, you can select miles earning option. You should earn 1 mile per $ spent.
BUT, even better...select point earning option and redeem them for a MUCH better exchange rate. For example:

MILES EARNING OPTION:
$6000 spent = 6000 miles

POINT EARNING OPTION:
$6000 spent = 60,000 marriott points
Then redeem 60,000 points for 20,000 miles, equal to more than 3 miles per dollar spent!
