We wre able to board when there was a small crowd. I asked the CM at the gate told to go up to ask the captain. If you board at the front of the boat, go up to the top level and look for the door marked PRIVATE under the wheelhouse. We did not get and answer to the knock right away, but there are no windows in the wheelhouse, so I called up to the captain and she came down to open the door. Our boys, 7 & 9, had a great time "steering" around the rocks and blowing the whistle. Found out later from my MIL who sat outside by the door that another lady kept rattling the doorknob while were up there.
