I know Dinorama is very unpopular, but I don't see "replacing" it as a good idea -- I'd rather see TDO focus on adding attractions, not replacing them especially with Triceratop Spin being one of the few rides in the park that all ages can enjoy. If they add Pandora (say 2-3 attractions) plus another land (Australia, Antartica, South America, Critter Country, whatever) with a few attractions, then we can talk about changing Dinorama. But I don't see the
point of spending millions to tear down Dinorama and then spending money
to replace it when they can just spend the total amount to build something
and still have 2 rides from Dinorama.
YMMV.
