Hi Lyn. You do not state whether the two hours is towing or solo. If solo try Widend Touring sit at Marldon near Paignton where there are seasonal pitches available and dog walks. Phone Julie on (01803) 550116. Obviously for taking the van down there you will need more than two hours. We can do it without speeding from Bridgend with the van in tow in 3 hours. Very good roads after M5 at Exeter, with possible hold ups on Newton Abbot to Torquay road. Alternative route is via Newton Abbot and Totness (not such a good road if towing).
Good luck in your quest.
