That and the charm of an outdoors crocodilian enclosure, in contrast to the huge amount of indoor crocodilians, even in temperate climates. Heck, even in my native Catalonia, the american alligators they have had in Barcelona Zoo and otherwise were kept in indoor enclosures, even though temperatures year-round in this Mediterranean climate are warmer than in the Oceanic climated New York. So, I guess it's fine to keep them outside.
