Makes the most sense for that show than any other. When dealing with the very limited launch/flight restrictions, 100 feet from guests, etc..etc.. would be very tough for them to be utilized at the MK. Epcot has some possibilities, but if it can't be over the lagoon, just thinking due to the fireworks taking place and possible fallout impacting drone flight, unless used during the Order segment of Illuminations while the globe makes its way out in conjunction with the fountain display and lack of pyrotechnics. It would be awkward if they flew over the waterway shown in the imagery next to the Odyssey. ROL makes perfect sense.
Or possibly as part of a replacement for RoE!
