We would like to travel to the States at Easter, somewhere like Boston but we're flexible on location really. We have two DC, one is 4 the other 7 so instead of traveling around the place in a hired car (which they would hate), we thought they might enjoy being in a holiday camp with set up activities and the like. Do any of you know of anything specific you could perhaps recommend? We don't enjoy the heat or extreme sports but apart from that, we just want to experience something different. TIA.
