We're thinking of doing a 4 night break at Haven Seashore Gt Yarmouth in March. We usually go to Centreparcs but just fancy a change (and obv it's much cheaper!) we have a 3 yr old and a 1 yr old sons who just want to have a pool and a playground really. ANyone been to Seashore before? What's it like? We would prob just use it as a base to explore the area.
