Does anyone know of good seaside resorts, on South Coast (not too far to drive from nr Heathrow)? I want to take ds (26 months) for his first proper visit to the seaside, over the next couple of weeks. Will probably just do a day trip, so don't want to be overwhelmed with a busy resort with loads to do. Somewhere not too full of other people!! Any ideas/recommendations would be much appreciated! Thanks all!
