I did it three weeks ago in 3 days with luggage, wasn't pushed for time at all and I stopped quite a bit to do touristy stuff. Once you've done the pull up out of Pateley Bridge to Brimham rocks you've done with the dales and it's a steady ride down through Fountains to Ripon. I'd look for a spot anywhere from Brimham to Boroughbridge to camp. Even if you stopped in Pateley it wouldn't be bad except for the climb out on cold legs in the morning, there are no real hills after that except for the lift up onto the Wolds after Pocklington, which is easy enough compared to the Dales.
I enjoyed the path around Morecambe, just a regular ex railway path, and once through Lancaster you're following the Lune and very nice indeed.
It's really well signposted, you basically don't even need a map while riding. I missed out maybe three times on the whole route, around Sainsbury's and a subway in Lancaster, in Clapham where I was following a cute blonde on a shiny Trek and not watching for signs, and in Pocklington where the signs seem to make a complete loop of the (small) one way system.
