One example is this one for July 1-5, Dupont Circle - Woodley Park
4*, Pets Allowed, Fitness Center, Restaurant, Non smoking, $72
On the checkout page you see: "Somebody just booked this hotel for $113.89", which is the same as the normal Priceline price for Kimpton Carlyle.
There is no mention of a resort fee
Downtown, 3.5*, $54, Free internet, Pets allowed, Business Center
This is very likely Kimpton Rouge. For this one I do see "Additional Mandatory Fee:$105.56"
