We have our elderly in laws visiting this weekend. I'd love to take them to a beach but my usual favourites (Happisburgh, Mundsley) won't be good for MIL as her mobility with steepish slopes isn't good. I can only think of Yarmouth as one that doesn't have a steep slope to get near, are there any gems I'm missing? If beaches won't work any nice rivers/broads where we can drive to get an ice cream?
