I will disagree with everyone else here. THV's are our favorite. If you can still get them (which you may not be able to), that is our room of choice. We request toward the south bus stop, if the shuttle isn't there, we walk to the grandstand and vice versa. I don't think in all reality that it's that much more hassle. For us a trade off is having our own house with no neighbors running up and down the hall, no one above or below you. Have you seen the shower? I can't get my DS 13 out of the shower there, he LOVES it! (OK he LOVES AKV-Kidani's also!)
I think each resort has a hassle going certain places when they share with other resorts. To each their own. We hated the bus transportation at BWV because it seemed if you were going to/from the wrong place it too took forever. Our friends love BWV, we didn't like it.
Anyway, we decided to stay at the THV's at Christmas to be able to fully get away from the craziness of the parks. Oh, and I made my reservations at 11 months out.
We've stayed at SSR, OKW and they're alright. I could take or leave them. I would stay at the THV's or AKV-Kidani every trip if I could!
