Just to make sure you are aware, Toy Story is considered "preferred" now, so you have to pay the extra $10 or so, and yes, even though you request it you might not get it, but since you paid for a preferred room you will be in Fantasia, Dalmations or Toy Story regardless, which are all nice.
We were there in September of 06 and really enjoyed it. We were in the Buzz section, facing the parkinglot, which was fine by us b/c it was easy to get to our car. We were very close to the pool, food court and the bus stop too. My 3 year old at the time was thrilled to be staying in "Buzz and Woody's House." We also never had to share a bus or wait very long for a bus to arrive, but we did drive quite a bit as well.
