The entrance parking lot is littered with tons of garbage so that sets a pretty bad first impression. Then, when embarking they forgot to undo a tie to the dock so the boat sat in an awkward position for a bit while they undid it (update: apparently this is normal, seems it's a spring line to help maneuver).
Also, a higher smokestack may help with the fumes on deck (update: the stacks are not functional). I reckon the front of the boat is best to avoid the engine exhaust.
Overall the cruise was fine, there isn't much space to rest your drink on the top level but I guess it's safer that way.
