Aww the irony…
In the original Anaheim Disneyland it may be a Small World after all, but that world’s inhabitants are getting bigger and heavier almost by the day. The passengers are getting so much bigger that they are actually causing the boats to bottom out.
Disney has decided to re-engineer the rides so that it can stand the weight of the growing population. When the ride was first designed in 1963 the assumption was that the male adult riders would average 175 pounds and the women about 135, which they pretty much did at the time.
Today, the Small World ride now must accommodate adults who often weigh more than 200 pounds, which it often cannot do. Increasingly, overweighted boats get to certain points in the ride and bottom out, becoming stuck in the flume.
The ride monitors attempt to leave empty seats on many boats to compensate for the hefty, but this routinely antagonizes the hundreds of paying customers waiting in line. When a boat does bottom out, a long line of other boats backs up behind it, their passengers slowly going mad from listening to the ride’s theme song.
