$58.00 for a one night stay. Good deal. These could have been wine stains, crayola stains, or (gasp) blood stains.
I wouldn't be amused; yet I wouldn't make a scene. Would have asked for another room. Would not have relied on management or housekeeping to clean it up. As it was a Priceline stay, at least you don't have to go through the aggravation of looking for some kind of recompense (re: miles and/or points).
Hope the rehearsal dinner was fun.
