we are planning a family trip to finland june/july. we hope to stay in helsinki for a week (appartment) then travel round possibly staying in cabins in caravan parks, for other 2 weeks. we want the kids(9,11) to play and socialise with other kids. does this sound plausable? any suggestions on routes? any ideas to keep the cost down? we also want to spend another 2 weeks checking out sweden and norway.
