To each his own I guess. I Love the 1 Bedrooms, but when I am trying to get those most of my points, or when I just didn't have that many points, studios are great. Its nice to have a bed and a sofa, since there are just two of us.
I haven't stayed in all the studios, but I have stayed at OKW, BLT, WLV and AKV in a studios. My favorite so far is AKV Jambo. In fact, (we just got back from AKV) I was really suprised at HOW much I liked AKV. We stayed in a Savannah view which I think was perfect. The room was a nice size, (as opposed to BLT), was in good shape, had the sofa/bed combination, and I really liked the bathroom area layout, with the sinks outside of the tub/toilet room, and the fact that were two of them! The full length mirror and its location (not on the bathroom door), was nice as well.
I liked AKV Jambo also as it had a good counter service that you didn't have to go outside to get to. If there was one thing I don't like about
DVC is the lack of good CS. Don't get me wrong I like TS restaurants, and Olivia's was a big hit with us in January, but sometimes... I just want a hamburger or mac and cheese.
WLV was my second favorite, layout is very similar, but the two sinks really was a major factor for me. Roaring Forks is also a good CS option, you have to go outside, but as WLV is so small, the walk is very minimal. Plus I just love the Lodge.
BLT is my third favorite, studios are small, but not a huge deal if there are only 2 people. I would not recommend it for more then that. LOVE LOVE LOVE the walk to Magic Kingdom! So glad I own points there for the standard view villas. Not as big a fan as Contemporary as I thought I was going to be though, the layout is just so confusing for me. (I felt like I needed Indiana Jones to find the workout room)
OKW, just has never impressed me, I really have tried to like it... but it just feels too much like a retirement community. The CS stinks, (sorry), and I really dislike the room layout, the sink, tub and toilet all in one room. Of all the DVC's its studios remind me the most of just a normal run of the mill (non disney) hotel room, even before the refurb. I think because of the 2 queens as we really like the bed/sofa combination. Of course that's why some like it, its the only DVC with 2 real beds. Of course Olivia's is its one saving grace, its great!
Hope this helps
