Had two holidays in Isle of Wight with my kids - plenty when i was a kid - we used to stay at the Orchards, Newbridge - a caravan park - also has camping. Last time i was there we popped in as mum was with me & boys so she could see where she used to bring me. Picked up the latest leaflet - camping facilities look good.
Am definately considering it for 2011 and some camping hols with SWK i hope. Boys are already suggesting it after having a break from it this year.
Shanklin is my favourite beach, the boys love Blackgang Chine & Robin Hill Park. We have done the dinosaur museums and a fossil walk on the beach. I would recommend it to anyone and so would my boys (7 & 10).
