We just spent 2 nights in a LM room with our family of 4.
I liked AoA ... theming was excellent. Main pool was exceptional IMO ... well beyond what you would expect from a value resort. Quiet pool was nice as well. Very clean and well maintained.
Food court was chaos during busy times, but fine during off times - this was the same experience we had at Pop. I thought our food was fine there, but we only ate one full meal there and that was dinner at 5:00pm. We stopped in at the food court multiple times, so that is where I get my "chaos during busy times, fine during off times" statement.
We only went to the MK during our trip, but bus service was the same as what I've experienced at any other resort - the service to the park first thing in the morning (we are rope drop people) was great, but unless you got lucky, the wait for a bus coming back from the park to the resort was longish. The bus stops are totally covered which is great (I don't remember them being totally covered at Pop, but I could be wrong).
The room itself was about what I expected based on online pictures. Again, awesome theming ... I didn't show my kids pictures of the bathroom, so they loved the grotto theme in the shower. The cooling fridge was a nice touch ... we kept soda and water in there and the temp was fine. We spent very little time in the room. The safe held our ipad, 1 Nook, 1 Kindle and a wallet just fine.
Housekeeping was great. I called for extra towels as soon as we were in our room and they were delivered before we even changed into our swimsuits. We had two towel animals when we checked in ... so that was nice. On our second day, I left a note requesting extra towels (again, for the pool) with our tip and we were given about 6 extra towels.
I really had no complaints. We were on the 4th floor facing the parking lot in building 8. I made no requests, but the location was fine for us - very quiet. I don't think we had to wait at all for elevators. It is a bit of a walk to Animation hall, but we had beautiful weather so it was pleasant. Plus, I knew it would be a bit of a walk based on reviews.
The resort was filled with families having fun ... very friendly atmosphere. We saw babies, little kids, teens, tweens and everything in between.
