I am thoroughly impressed with the OP's demeanor through all this. They must be a practitioner of transcendental meditation or something similar. The thought of jumping into bed and then realizing I am laying in someone else’s urine would unleash a fury that would most likely end with the police being called. Somethings can be brushed aside ex: a used towel from a previous guest left hanging, a few drops of urine on the toilet seat, heck, even a small stain on the bed sheets I could get over. However having a bed with still wet urine on it raises it to a whole new level. Marriott corporate should have already comped the night and sent a $1000 Marriott gift card, with a hand written apology from the GM of the offending hotel.
