One day the St Quentin campsite may re-appear. In 2011 the temporary one was ok. I left everything pitched on the site for the duration in 2003, 2007 and 2011. If no campsite I'll probably do a cheap hotel again.
Definitely Newhaven-Dieppe, having done Portsmouth-Ouistreham [and Eurostar once]. We got the overnight ferry, rode to the Vernon F1, partly on the greenway [Avenue Verte], had a leisurely evening meal in town, then rode into St Q by late lunchtime, I think. We rode directly back to Dieppe, 100miles or so, just time for a meal then got the overnight boat again - preceded by fireworks for the Dieppe Raid commemorations.
