I think POP is much noisier. There were noisy kids running outside our room too, but that can happen anywhere, I suppose. We've stayed at ASMo five times and I haven't personally experienced noisy kids there, but I'm sure it happens sometimes. But at POP there is definitely a lot of noise coming from other rooms - voices, toliets flushing, showers running. Apparently the rooms are better insulated for noise at ASMo, because I've never heard any noises from other rooms there.

) was actually an invaulable tool for me to fall asleep.
I heard kids at the pool very late at night. I know it's to be expected to a certain degree, but I also like to get some sleep on vacation. I vote yes for the noise machine, I think it will definitely help!
I guess that can happen at any of the resorts though. Like many have suggested, I'd ask for a room at any of the sections that face the lake where it tends to be quieter!
