Actually the noise level was great. The rooms, or at least ours, was set back off the beaten path. The horns never woke us up (and I'm such a lite sleeper, my dh's snoring can drive me bonkers). If you're out on the balcony eating or just sitting, of course you can hear them, but it's not an annoying horn sound. Actually the sound is almost soothing, It gives you the feel that the ocean is literally just over the horizon. The whole Epcot resort area is really done up nicely. I guess it's true, no one does it like Disney.
My husband, who was not looking forward to this trip...(I always have to beg him to do a Disney thing), enjoyed this resort so much, we honestly tried to stay longer, but couldn't get plane reservations switched. Any of you that will be staying at this resort will have a truly magical time.
