I am looking at four nights at Casa Magna, Puerto Vallarta. The Marriott website quotes me $161 per night for an ocean view room. Using Kayak, all of their partner travel sites are quoting $129 and Priceline is $119. Rates do not include resort fees or taxes. Is this common with Marriott - do they price higher on their website? I am a Gold Elite trying to get Platinum so I would rather not use a partner site but $120++ is a significant amount of money just to get the credits.
