As stated, it's all personal preference. It's actually nice to run in a crowd with a mix of both. When we were tied up next to Stan in his 48DA to watch the Blue Angels a few weeks ago, it was great to have his back deck as a place to hang out and socialize. His margarita machine didn't suck either.
The social space on my flying bridge is similar to that of a dancer, but it is up a flight of stairs. This can be a good thing or a bad thing. I don't mind segregating the kids somewhere other than where I am. And usually when we're underway, the adults are upstairs with me and the kids are down below watching TV or playing Wii.
As far as salon noise, it's really not too bad. The hatches are well insulated and the carpet cuts down on the noise too. I'm surprised at the relatively low noise level because if you open the lazarette hatch at speed the noise is unbelievable.
Docking: there really is no problem once you get used to it. As 400DB said, you can easily see the aft port corner down the stairs and as long as your slip is wide enough, get as close as possible to the port and the starboard should be fine. Also, if there is a piling to starboard you can easily see that too. The visibility thing is overrated. You can't see the back of your car, but you can parallel park, right?
We use our boat nine months a year, going in the water in March. When we're in downtown Baltimore on a crisp late winter day with the salon shades pulled full open and the sun flooding in the windows it is remarkably pleasant. Similarly, when we're at anchor with a beautiful sunset cooking in the distance, we can all be sitting around the dinette table in air conditioned comfort taking in thee 360 degree panoramic view.
Plus, I think bridge guys just like looking down on other people. But that's another whole story.
