beanboon said:I don't think there is any way the waterways could be connected. The 20k water was filthy with diesel fuel (just look at the waterlines on the boats, they're black), the small world boats would likely have similar issues.
Considering how strong the smell of diesel and chlorine was there is no way you could run that water through a closed show building like small world without it being obvious.
The thing about fuel is it is very easily filtered from water in an enclosed environment as it doesn't mix with the water. I would hope with the size of 20k lagoon and the number of run throughs per day of the boats that they would have some sort of filtration system for this if the boats ran off of Diesel. Honestly I don't know.
Another possible explanation taking into account the leveling between IASW and 20k is that they may be connected to the same draining mechanism and resevoir system so to completely dismantle 20k they would have to rebuild the draining system for IASW, which may be included in the IASW rehab.
Anyway, another intersting thing I found on MagicalMountain.net is that some of the Nautilus submarines are sunk off Disney's private Island, Castaway Cay. Can anyone confirm that? http://www.magicalmountain.net/WDWArchives/20000Leagues.asp
