I'll give you the pool area being weird. I can't argue that, but really the room dark? We had to shut the curtains in our Villa to get decent room shots, it was so bright in the rooms we loved it. But that was with a PP view.
I can see that the other views might have darker rooms over all. It's been so long since I stayed in a regular room I don't remember what they were like. I'm sure you will have no problem getting a one bedroom at 7 months. Probably you can get the studio as well If you look midweek and not over President's day weekend. If you book during the first week our stays may overlap.
With your mother and family I would really suggest the one bedroom if you can swing the points. Separate beds for mom and DD. Two bathrooms, jacuzzi tub for the wife, what's not to like?
Our room faced the front parking area. Even with the shades open I thought it was very dark. Dark wood, dark green carpets, dark upholstery. Maybe the DVC rooms are different. The view was awful too, but these were the rooms given to ABD so it didn't surprise me. The view certainly didn't bother me, because we were in our room awake for probably cumulative 5 hours over the 3 nights we were there. I can imagine a view out to PP would brighten up the room significantly.
I'm hyjacking my own thread here

but yes my plan is to try and go during presidents week, but certainly not over the weekend. If we do a studio, I would try to come in on Monday (Presidents Day) and stay 4 nights - would cost 68 points. If we went with the 1-bedroom, I would only be able to do 3 nights as that would run us 93 points, and that is at the upper limit of the points I'm willing to use. (I have 50 - 2015 UY points, and I need enough points for a week at WDW later in 2016 - this would leave me with 117 points in my 2016 December UY, if I went much more I would need to buy more points, which I don't want to do.) In that case, we would probably still make the drive from Phoenix on Monday and just stay somewhere nearby in Anaheim for one night, and then check-in at VGC first thing on Tuesday. I don't think our trips will overlap though, because I think you usually go earlier in the month.
I do agree the 1-bedroom would be more appealing. Before my Dad passed away, we were definitely going to do the 1-bedroom, and I was going to give my parents the main bedroom. Now with just 4 of us, I am keeping the studio in the running, but I am probably still leaning slightly towards the 1-bedroom, for the exact reason you say...we could have the sofa bed for my mom and the sleeper couch for DD and a room for myself. In addition, we could bring some food from my mom's so we could eat a few meals in the room and save on other expenses there - which would make up for spending the extra night. There's no way we could swing it for a week, but for the three nights it seems doable.
Actually, I would be happy with either of the two options, because without being able to use the DVC points, I am not sure we could afford the trip if we needed to pay for the hotel along with everything else. Swinging it this way using points that are already part of our annual spending budget makes it possible.
I still can barely conceive that I could be staying in a place so nice.

I'm typically a "Tropicana Inn and Suites" type of guy...
