Famed attorney Robert Shapiro thinks there's little doubt ... Disney is going to pay dearly for the alligator attack that resulted in the gruesome death of a 2-year-old boy.
O.J. Simpson's former lawyer was leaving Madeo Thursday night when our photog asked about Disney's legal exposure.
TMZ broke the story ... neighboring resorts specifically warned of alligators, but the Disney resort in question only had "NO SWIMMING" signs. Fact is ... the 2-year-old was not even swimming ... he was wading in 1 foot of water.
Shapiro thinks Disney's gonna have to open its wallet.
