DK Eyewitness "A lavishly landscaped pool features waterfalls, a waterslide, whirlpools, and a children’s pool, while the on-site dining options include a casual 1950s-style diner and a full service Mediterranean-style restaurant"
Oyster "However, rooms are on the small side and lack full kitchens, but there are a few dining and drinking options on the property, including a casual, diner-style restaurant"
