Hi Tom,
We did belgium and holland last year, did the crossing on the eurothing 40 mins and we were in France, and stayed with Canvas holidays, who were great, allowed us to park the bikes right outside the caravan, and even let us in after the gates were shut at night. We had a great time and even the police encouraged us to use the righthand on the motorways. Alternatively you can go further to Germany, my mate has a bikers hotel which is in a nice part of germany with lakes where you can go swimming and Simon runs ride outs into the mountains.
http://biker-hotel-harz.de. Thats about 350 miles from Eastbourne, with loads of stops and eateries en-route.
Great time to be had by all, have stayed there and had a wonderfull time.
Or there is the Bikers Loft if its still in existance in Belgium, bikers and pillions only though.
Have fun.
