While not a 10 day stay, I was just looking for a Friday evening stay in July in a suburb of Columbus OH. Anything close to where I wanted to stay only has rooms for sale not pts. Went to my SPG account. Found a 4 pts across the street from the FI I wanted to be at and booked for 3K for the night.
Why can't marriott just have a freeking room for pts if they are willing to sell it! That is where I get frustrated.
