I have been waiting for this pool to open for nearly a year. Keep bringing a bath suit bc they say it’s either open or will be open by the 3/6. Didn’t happen. No snacks and restaurants close early in the area. Also restaurants are extremely expensive.

Clean rooms. Staff was friendly. The only down fall was the really small bathrooms and the 60.00 a night garage parking. Other than that it was a very convenient place to stay with kids since its located close to the wharf.
