A pace of 200k is quite doable. I have done a ride of similar length in that sort of time and not needed any overnight riding. However the days are long and I think camping would add so much faffing to the effort that you'll probably enjoy it less at that sort of pace.
The rhythym was basically get up, breakfast, ride all daywith only food breaks, check in, shower and wash clothes, eat dinner, two beers, check cycling clothes drying, sleep, get up, breakfast.... a hotel with a restaurant each night doesn't half help.
