It's an unwritten rule for Florida residents: Keep your kids away from ponds and lakes because alligators are everywhere.

But after a gator killed a 2-year-old Nebraska boy at a Walt Disney World Resort, attention soon turned to tourists. In a state with an estimated 1 million alligators, how should theme parks and other attractions warn visitors, and did Disney do enough?

Disney beaches remained closed on Thursday after the death of Lane Graves, and the company said it has decided to add alligator warning signs, which it previously did not have around park waters.
