Another vote for the 210 - a most underappreciated aircraft IMHO. Had one two summers ago and liked it a lot. It was a 60s vintage and great value for money.
The 3rd row of seats were fold-down items that wouldn't have been any use for anything but small children. But the fold-down provided a nice luggage area.
A nice, big door each side - easy to get in and out.
Good performance with four lardy adults, bags and fuel.
Just as many 4-seaters are 2+2, so many 6-seaters are 4+2......if you really need to haul 6 grownups and bags that often then you probably need something a bit bigger.
Beechcraft are all lovely but cost a fair bit more than most Piper/Cessna options like-for-like.
