The medical center continued to operate into the 21st century, but closed after Hurricane Katrina's storm surge caused the collapse of one structure and flooding of the other buildings to a depth of 4 feet (1.2 m).

When the new resort opened, it had two hotels containing over 200 rooms, two full-service restaurants, a 3-acre (1.2 ha) water park (splash pads, slides, pool), and a wedding chapel so as to accommodate both business and family clientele.
