I think you will find the period of adjustment to be over quickly. Dual engines located 20 feet +/- apart make maneuvering a dream. The viz can be limited but having somebody forward to relay info solves most of that. I found that that wasn't even necessary most of the time after you get used to it. In slow speed situations I'd leave the wheel, walk over to the side and look for myself. You also develop a feel for the edges of the boat, akin to "knowing" where the edges of your car are when parking.
As far as little crew going above in the night time I dunno. Threats, bribery, locked doors, alert adults? I will say that the acoustics of many cats are not as silent as one might wish. Something to remember on a romantic evening with extra crew aboard.
Try it you'll like it. Warning: You may not get your family back on a mono.
