As I recall the couch in our DLH room turned into a small bed. Depending on the size of the person, though, you could probably just sleep on the couch. Perhaps someone else knows for sure.
I'm not sure that there is anything horribly wrong with the Paradise Pier although we won't stay there again. They just closed the entrance to DCA that we did use while there so now you have to walk to the front of DCA to get in -- so that perk is gone. They aren't expecting to open the one from PP back up again --- too high of a cost for maintaining it --is what I heard.
The decor inside the room is ordinary -- nothing spectacular. But nothing horrible, either. Just ordinary. One thing we didn't like is that we always saw dishes in the hall from room service - they weren't good about picking them up -- no matter what time the day. Looking at stale food that has been there half a day was just not very appealing. And, we were close to the end door at the end of the hall and people would go out there and smoke. They would then prop open the door and the smoke would drift in the hall. It was like walking into a smoky bar when you were in the hall. Then we had to put a towel at our door to keep it from coming into our room. But, the room was clean just fairly plain compared with the GC and the DLH. And, it is further to walk to get to the parks, especially now since the entrance to DCA is closed. The view on the theme park side is fine. It does overlook CA and is very pretty at night. But that view does cost more. The other thing we didn't like is the fact that the windows only opened a crack. So even though you had a view you didn't have a balcony. Although there was not a balcony at DLH but the slider door did open to the outdoors which is nice depending on what time of year you do go. The GC does have balconies and they are very nice, especially in the evening. And, if you have a downtown disney or theme park view you can do a lot of people watching.
The service was nothing spectacular at PP, either. We were in concierge and felt as if we didn't get any more service than if we had paid the regular room rate except for the use of the lounge. Unfortuantely when we would go to get water, pop or juice it was usually warm and not very appealing. When we did ask for ice it took them 5-10 minutes to find some. And, then they would bring you one or two ice cubes. The lounge itself was okay but the one at DLH much better with longer hours and a very nice view of Downtown Disney and evening fireworks where they pipe in the music to go with it. Food selection, we thought, was better and more varied. At DLH they also went out of their way to "serve" you here they were just sorta there but not much more. We didn't find this to be the case at PP.
The pool hasn't really changed much since it was Pan Pacific. Square pool that they stuck some plants around. They put in a slide that is by itself and doesn't go into the pool. My DS6 liked it but prefers the pool and slide at DLH and GC better than PP. There are no "grounds" per say at PP like at GC and DLH. But the rooms are clean and have just been refurbished.
I think it will depend on what you want. If you just want a place to lay your head, I think it is fine. If you are looking for the magic we just found more of it at the DLH and the GC.
