(1,002 reviews) The Cheshire is in a class by itself. The halls and sitting areas are so full of history and there’s an ambiance that we just love. Our suite, Treasure Island, was amazing! Large, clean, luxurious and cozy with a beautiful fireplace and large jacuzzi. We had a delicious dinner at the Basso, relaxed in the very British, cozy Fox & Hound, enjoyed a coffee at the Tudor styled Starbucks and as always, enjoyed breakfast beside the fireplace. We loved our stay!
