Actually both the Steamboat Landing (now called the Wharf at Steamboat Landing) and the Hideaway are open. Steamboat Landing was never closed and the Hideaway just reopened. They are actually located in Glen Cove Marina which is at the end of Glen Cove Creek.
I was actually just talking to my buddy about this an hour ago as he keeps his small power boat in that harbor. We planned to sail my boat there the 2nd week in June to stay at Steamboat landing and get some food. Can't wait as I havn't been there in my own boat yet.
