I think it was back in 1990 - was at DW for my first solo vacation and got stuck in IASW. At first, the first 15 minutes that incessant, song REALLY gets to you but what was worse? is that we were in the area where they sang it in another language. I was in the front of the first boat with some little kids and their Mom behind me. There was another boat behind us but I couldn't make out their speech - it sounded like clattering typewriters.
After 15 minutes, the music stopped and all the lights went out. Total and complete pitch blackness. The little kids started to whimper and then cry. No soothing CMs to check on us, nothing. It was so black you couldn't see your hand in front of your face. I had a light on my watch and after 10 minutes, I decided I had had enough! I climbed out of the boat - the water is only 3.5 feet deep. Climbed on the catwalk and used my little timex watch light to try and find a way out to get help. One of the men in the other boat had a lighter and he tosses it at me - it's probably still at the bottom of IASW! (Piece of advice: If it's really dark, throwing something at someone unless you alert them, has a slim chance of being caught).
I found a door and pushed it open - there were CMs on the other side but they couldn't get in -they told me later they were magnetically sealed. It turns out that lightening had struck the WDW transformer and their backup generator only did so much.
As for the people in the boat behind me - it truly is a small world after all - the boat contained my best friend and her family. They're from Argentina and I hadn't seen her in 10 years!
Doo-do do-do
BTW - CMs were glad I took initiative. Since I was soaked - they gave me Disney clothes and their limo took me back to my hotel. They gave me a limo for the rest of my stay and when they found out about my best friend - they treated all of us to dinner at The Contemporary. Now I don't mind that song so much.
