Hi, we're just back from POR and we LOVED IT!!

We had a corner room in Parterre Place, it was non-smoking and right across from the bridge, plus we had a quiet pool practically right outside our door, which was both lovely and actually quiet. Although we were on the first floor and the resort was full, our room felt quiet and private.
However, at check-in, ask the CM exactly where your room is on the map. We were shown an intial room in Acadia House (too far away from what we wanted) and then I asked if we could be closer to the main building. She then showed me the exact location of a few room available in other mansions. I got to pick the one I liked best. We had reserved a "water view" room. I've heard others say it wasn't worth it, but at least it ensured that we weren't in the back of the mansions. We checked in very late at night, and there was no one around, so I think the CM had time to be extra helpful.
In terms of busses; we were just a short walk over the bridge to the bus stop in the front of the main building (south depot??). Often the bus filled up there and went right onto the park. Also it was the first stop (usually after POFQ, but sometimes not even that) on the way home. Also, since it was right at the main building, it was convenient to then stop off at the food court for a piece of fruit or a quick snack to take back to the room and the pool.
Hope some of this helps. Enjoy your honeymoon. I loved seeing the couples wearing their bride and groom mouse ears. I always wanted to do something special for them. Once we had fastpasses to Splash Mountain that we didn't want to use since we were ready to go back to the hotel. I found a honeymoon couple to give them to.
