Do yourself a favor and stay a few doors up at the Hilton garden inn. Staff is great and hotel is so much more friendly.
Yes, unless the particular room you book has an exclusion. Not all double bed rooms are created equal at all hotels. If not available, it should be stated in the room details when you pull up the description. Some hotels run short of rollabeds so I would put the request in at the time of booking.
