So Cosmopolitan takes $30 a night for a resort fee. I'm staying a week, so that's $210. Does this include tax or do I have to add tax on top of that? If so, how much would I have to hand over? Also, when do the Cosmopolitan take your resort fee? Is it at Check-In or Check-Out? Just need to know so I can save some cash for checking out (if it is then).
