Unfortunately, the resort fee policy varies somewhat by property and property type e.g.:Free Nights at Participating Caesars Rewards Properties do not include resort fees, optional services (such as, but not limited to, parking or pet fees) or incidental charges (such as, but not limited to, long distance telephone calls or movie rentals). Resorts fees are charged per room, per night and vary by property. Contact the applicable property directly for specific fee amounts.
