PAB is the longer run (about 12 hours) and is the one open only for the season.
The one thing that I don't like about the ferry is that they now won't let you sleep on the inside or outside decks, just in the chairs or the benches; at the same time they really don't provide enough sleeping compartments or bunk rooms, so one has to book early to get sleeping.
More or less the same problem exists on all ferries, like the one to Alaska -- It irks me no end to have my home and comfortable bed right down there a deck or three and not be able to use it...
I usually find a gas station - eatery near the port when I disembark, park and take a nap -- The Newfs are cool about stuf like that.
I recall one "mainlander" from Toronto with a big 5W remarking "I'd bet if I just pulled up on some Newf's front lawn and started unhitching within a few minutes he'd come out with an extension cord in hand, remarking that the wife had just put the tea kettle on". I've traveled a lot and lived in some moderately strange places and my experience is that the Newfs are the friendliest folks I've met, and they even speak English (altho most of the other Canadians may deny that!) -- I had no trouble understanding them, but that may be because I spent a few years in New England.
If one wants to get a taste of life with Newfs (Newfie, BTW, is more of a put-down term except when the Newfs themselves use it), I suggest reading "The Shipping News" and the excellent "The Boat Who Wouldn't Float" by Farley Mowat (author of "Never Cry Wolf" which was made into a movie). Mowat is not revered by the Newfs as he painted them in a less than favorable
light.

Newfs have a reputation as party animals and until recently a vacation pastime was to pack up family and friends and RVs and tents and pitch camp in a local rock quarry, enjoying life to the fullest. Sadly, the quarry owners, fearing liability suits, started blocking the entrances with boulder.
In summer, one also sees RVs and campers parked in the open gravel spaces at highway intersections. There are lots of Provincial and private parks, plus the National Parks, esp Gros Morne.
