We celebrated my nephew's 3rd birthday at Strawberry Fields with one of their Party plans. A bit of a drive for us, but if I lived up that way, I would definately consider it for the girls. They loved it. (Though the teenage party host could have been more interested and engaging :)
Party games, Cake, Strawberries, Picking with Grandad, Grandma Kisses, Spoilt by Aunts and Uncles, Warm sun.. what more could you want?
