We just returned from our first stay at POR. We stayed in bldg 18 in Alligator Bayou. Our room had a trundle bed. This building was in a great location. Right next to a quiet pool and a short walk to the main building and the bus stop.
The CM actually asked me at check in if I had a preference of Magnolia Bend or Alligator Bayou and I simply asked for a building close to the main building and bus stops and that's where they put us. I was very happy with our room.
The resort was very quiet when we were there, the parks were nearly empty and we didn't wait in line for anything. The resort must not have been very crowded either because we never had to really wait in line at the food court either and I've heard that it can get pretty busy down there @ mealtimes.
Well....I wish you luck and have a great time!!!
