Sandown -good to just pop in to for a quick cuppa and buttie. Or taxi in to Sandown for the great British seaside experience.
Bembridge -walk thru the Holiday Park to the cliff top (out of airfield, left, immediately right up lane, left, 100yds, right up gravel track past indoor swimming pool and caravans on your left); 45 min walk along the cliffs to the Crab & Lobster at Bembridge (get there early!!) If tide out, walk along the beach back to the cafe, quick cup of tea and cake, then up the path back to the airfield.
Done this so many times, even taken our hound (but dog ban on beach May-Sep...).
Have fun!!
