I've just realised it's a bank holiday this weekend and we have nothing planned. We = two adults, a 4-yo and 2-yo.
I feel like a day trip to a seaside town within an hour's train travel from London could work. Something like Brighton but maybe calmer/less busy? The little ones love all the usual things - playground, seaside, bit of relaxed shopping, coffee shop/cake.
Can clever MNetters help me find a good place? (We've recently been to Southend and Broadstairs, so not those again please.)
