I was looking at allearsnet.com and I saw the pics of the king rooms at S/D. I was wondering if the sofa makes out into a double bed? We will have 8 of us (2 rooms), and 4 are teens, so could the teens sleep on the sofabed (assuming it is one)....or is it a single sofabed? (that is at Paradise Peir hotel in DLR.). Thanks!!!!
