I had a mixed experience at Wentworth By The Sea. The beautifully landscaped grounds and the pool with great seating overlooking the water were definite highlights, but the $500 nightly rate felt excessive for the quality of the room. While I enjoyed the dining options, like SALT Kitchen and Bar, I was disappointed with the lack of free coffee in the lobby and the plainness of the rooms.

I was excited to stay at Wentworth By The Sea, but the experience was mixed. The location is absolutely gorgeous and the views are beautiful, though the service was disappointingly poor, contributing to a less than satisfactory stay. The food was hit or miss, with some dishes impressing while others fell flat, and the room itself was in need of updates. Overall, while I appreciated the ambiance, I left feeling that I didn't get the value for what I paid.
