I remember going to Clacton on Sea. There was a Butlins there that had a cafe/ bar 'under' the swimming pool and we watched peoples legs in the water as we drank our drinks. Bet its not there now.not a best day out but a vivid memory. One of best days out was at Chessington before it was a theme park. I must have only been about 4 cos the photos are in black and white but i remember it clearly.
