I'm currently on holiday with DH and 4-month-old DS. They have provided a cot but the bed is just so perfect, we haven't bothered with it. It is huge, bigger than kingsize, and is in a corner with a wooden surround on two sides. This means there is space for books, glasses, spare pillows etc on the ledge around it. There is tons and tons of space for all three of us, with DS closest to the ledge thing, then me, then DH. There are separate single duvets which meant that last night I could feed DS lying down on both sides as I could take my duvet with me to each side, IYSWIM. It is just perfect! It's BLISSFULLY comfortable too. I never want to go home - our double with co-sleeper cot is going to seem very small!
