When a man invites a woman to a weekend in Hawaii, and she insists on separate rooms should they split the expenses or should she pay for room?

Did he know before they flew to Hawaii, that she was going to insist on separate rooms? If so, shouldn't he pay?

If he didn't know until they checked into the hotel that she was going to insist on separate rooms, would he be an a$$, if he paid for the one night. left early the next more and asked for a refund on her her return ticket?
