I'm going to Centre Parc Woburn in a couple of weeks. I know they have travel cots in the lodges and not the wooden cots like other Centre Parcs do. Does anyone have any experience of using the Woburn travel cots? Are they comfy? Do they have a decent mattress? I know my travel cot only has a thin padded base, which is ok for one night's sleep, I'm just worried about my little one being comfy for a week in a travel cot, or do I bring my own mattress???
