It's been running forever, on our first Disney stay, back in 1977,, we were at the CR and heard this music and saw the lights out our slider and ran to the dock. It was marvelous and couldn't wait till the next night to see it in its entirely. It has a route and visits all the resorts on the MK loop and WL and FW. We stay in the MK area resorts and try to catch it a few nights, greatest free thing going, even after all thses years.
