I honestly wouldn't mind that at all. Kumba has never had more than a 10 minute wait (and that's on a very busy day) in my experience, and even if they have to start using the reservation system like Kraken I don't see that as being any different than the FastPass+ system at Disney that basically forces you to plan out your rides weeks in advance. Also, the corner of the park where Kumba sits could really use the makeover that invariably accompanies every new ride at SeaWorld and Busch Gardens.
