We have just stayed at Doubletree Guest Suites in Times Square and they sleep 5. It was absolutely fantastic and we will stay there again. Great spot, friendly staff, very clean, massive rooms (well two rooms). I booked through Expedia when they had a 10% off sale and I got the room cheaper than booking direct with the hotel.
If you go to my TR (aussietravellers adventures) there will be photos of the hotel rooms somewhere on the first few pages
