A free room can cost as little as 1,000 Rewards Credits at properties like Flamingo and the Linq since you can use your points to pay for your hotel at at 100:$1 ratio. If the rate for your hotel is over $150, it would make more sense to transfer 15,000 Caesars Rewards Credits to Wyndham Rewards and book a free stay thatv way since the Caesars properties are 15k points a night.
