Rack My Points...
 

Rack serious MyPoints by booking all hotel reservations through USAHotelGuide.. Go to http://www.mypoints.com then Shopping, Then Travel. USA Hotel Guide is on page 2 or 3..

2 points per dollar spent racks up serious miles PLUS you can still get your hotel miles (Marriott Rewards, etc..)

Marriott prices are identical to the ones given on the Elite hot line.

In theory, it's a great way to accrue Mypoints. In practice, you'll have to call them each time (sometimes more than once) to have the points posted, then wait several days... But that seems to be the way with most of the purchases that go through Mypoints.

I have had to email them my 'Receipts' but they fix it quickly.

After complaining a few times (and making suggestions) I think they finally fixed it. My last few seem to have been posted correctly.
