As an avid reader of LA Times Travel I saw Granada's new $140 offer this last Sunday and called to book it. It clearly stated Monday-Friday through end of June to include room, wine tasting for two & picnic lunch. When I gave her my dates she said Fridays aren't included, so when I told her I had the paper in hand, she put me on hold and came back and said "that means check-out on Friday and that it's a standard in the industry to state it that way". Then why do all other honest hotels quote/advertise by the night (i.e. look at all Vegas hotels who clearly state Sun-Thur to get the lowest rates)?
Bottom line, at most it's deceptive and at the minimum it might have been a typo, but don't lie to a prospective customer - just honor it!
