Waste of time and money. We took the 2.5 hour tour. The audio was terrible - imposssible to hear at some points, so loud your teeth rattled at others, and they kept playing the wrong clips at the wrong times (we heard about the kitty litter factory 7 times). They eventually stopped playing audio altogether. Boat was full of loud children running amok.
