We are staying at Pop Century this time round, so no fridge. Does anyone know of where I can get a small cool box from, something to hold a pot of butter, some ham, couple of yoghurts, that kind of thing. I've heard that you can get polystyrene ones but I haven't a clue as I've never needed one before. I don't want to spend a lot as it will only be for our two weeks unless I can cram it into our owners locker for another year. Any suggestions peeps??
