9.2/10 Wonderful! (1,140 reviews)
We had a fabulous stay. Staff was helpful, restaurant was good and pool/ beach area was fabulous. I debated between a waterfront ocean or the bigger studio room. I am glad I chose the waterfront king, the location was amazing and with the studio you would need to cross route 1 for amenities.
