I agree, we had a fab holiday there this year. Loved the West coast, Ventor and the areas around, lovely quaint seaside towns and beautiful countryside, but the East side (Shanklin etc) we were not so keen on, a bit chavtastic (apologies to anyone who lives there!). We stayed at Orchards caravan park, quite nice, indoor and outdoor swimming pools, nice facilities, quite fmaily friendly and a good base for exploring but quite a big site, if you like small bijou campsites a la cool camping it would probably not be for you. Also liked the look of Cowes but we were only there for a few hours en route to the ferry.
We went for second time this summer - to Seaview/Nettlestone (Bembridge area). Lovely old-fashioned tip out to the beach every day type of holiday. Didn't rain this time (apart from early morning/ times we weren't wanting to go out) so hit lucky too.
