We were there in October in the LM room and had a fantastic time. So much so that DW and I were discussing the possibility of us going back in the future and just staying at the resort. No theme parks, just a resort stay.
I have read reviews where visitors have encountered hearing noises thru the walls, could hear the toilets flushing from the adjacent rooms, lineups at the cafeteria, etc. Thru my experience I didn't encounter any of this. The toilet is loud though. I didn't hear it being flushed in the rooms surrounding ours, but it did scare the crap out of me every time it was flushed.
I have also read a few reports about the long travel to the Magic Kingdom. Maybe I'm just oblivious to these things 'cause I didn't find it to be a long trip at all. Also concerning the wait itself for the bus, there was one time we waited about 8-10 minutes and that was to go to Downtown Disney. Every other time was within 2-3 minutes. As a matter of fact it surprised us when we were returning from MK after MNSSHP the bus driver told us to get on board. The bus was completely empty and we told him we were looking for the bus to AoA. He said we've got the right bus and sure enough along came everyone else, the bus was loaded within 5 minutes, and off we went.
Each experience is different I suppose.
Enjoy your trip!!
