SInce I'm a Canadian, I never really paid attention to DC US, since it wasn't applicable to me. However, earlier today, while surfing marriott.com I noticed a redemption rate for DC points to Marriot Rewards Program that didn't looked right to me (as a Canadian!!)

1250 points from DC US for 1500 MR points.

That got me thinking and I went to look for the Canadian DC website and noticed that the same reward was way more expensive in Canada then in the US

2250 points from DC Canada for 1500 MR Points

I also noticed the same thing for all the other hotels programs.

Why is the price difference so high?
