Our stay at Wentworth by the Sea was overall delightful, with beautiful holiday decorations enhancing the charm of the hotel. The dining experience was top-notch, especially at Salt, but I noticed some inconsistency in service that could be improved. The rooms were comfortable with a lovely view, although I wish there had been fewer crowds during our visit. The surrounding area offered great walks and activities, which made for a memorable trip.

I recently stayed at The Wentworth and had mixed feelings about my experience. While the scenery was stunning and the hotel's historic charm greatly added to the ambiance, there were several issues that left me disappointed, particularly with the service and maintenance of the facilities. The food was enjoyable, but the overall service didn’t meet my expectations given the price of the stay.

I enjoyed my stay at the Wentworth, especially the spacious Marina suite which was perfect for our family getaway. While the pool area was lovely and not too crowded, I found the service a bit lacking, especially considering the high prices. The dining experience was superb, particularly the Lobster salad, but some communication about menu changes would have been helpful. Overall, it’s a beautiful and charming hotel, though improvements in service and communication are needed.
