oh. . disagree completely.
at BGT, the Gorilla/Chimp Path, the Lions/Tiger Path, the Kangaroos/Wallabees, the bird sanctuary, the Crocodiles, and the "hidden path" that features the hyenas & the Hippos you mentioned.
and the biggie.. feeding the giraffes by hand on the safari (upcharge but worth it), and the Serengeti plain that's veritable from train and from the restaurant?
we LOVED BGT.
we also loved BGW.. it's just going to depend on what you prefer, the animals, or the overall feel of the park & Rides.
tho BGW has better rides (in my opinion) and is an absolutely stunningly gorgeous park, we liked BGT just as much, only for different reasons. . the animals.
