Aren't the shows in Disney seas very similar to RoL, from the Wiki page of BraviSeamo
"the BraviSEAmo! project and development included several technical firsts for Disney Parks shows. It was the first to use a Global Positioning System (GPS), which was used to track the four fountain barges and correctly locate them in the lagoon to ensure the fountains and pyrotechnic effects would be launched from their proper locations. The GPS was also used on the two largest show barges, the Mickey Chariot barge and the Bellisea barge, to help the operators correctly place them and hit marks in the lagoon." I understand BraviSEAmo had drivers for a lot of the floats but i believe the fountains were moved by GPS, if that's the case then i dont see how Disney would have issues like that. (i'm not sure how a lot of shows work so don't judge me
.)
