Looking at a four night stay in February in an ocean view premium room.

Using points, it's 70,000 points per night, less fourth night free, or 52,500 points per night.

Using the current purchase promotion of 0.005 per point, that translates into $262.50 per night + $80 resort fee, for a total of $342.50 per night.

Cash rate is $1,339 per night plus $227 in taxes and fees, for a total of $1,567 per night.

Am I missing something?
