Fine, a fireworks show. That's okay. For now.
But THEN TDO should start making plans for a PERMANENT installation of Frozen in DHS, and make it stellar. I mean, Tower of Terror-level stellar. A major E ticket. Put the kingdom of Arendelle in the Streets of America area. Put a Frozen castle/dark ride where the Muppet courtyard is. Put artificial trees with "snow" and "ice" on them everywhere in those areas. Theme the HELL out of it. Who wouldn't want to walk into an enchanted land of ice and snow in the middle of balmy Florida? Christ, the possibilities are incredible here. But ONLY if TDO will grow a freaking pair and loosen the purse strings. Prove the Disney Imagineers aren't just faded has-been hacks.
Otherwise, Universal will eat Disney's theme-park lunch. End of story.
