My heart just breaks for this family and the tragedy of losing their young child this way. (or any way for that matter). I agree with many on here that are not placing blame on these poor parents and their unawareness of dangerous wildlife or unsafe water at WDW. We were just at the VGF and left last Friday. While we were there on that very same location and beach I had to tell my 25 year old nephew to stop wading in the water while we were on the beach in the evening hours. He was completely oblivious to the dangers of gators, snakes and other hazards.
I'm aware of these things because I've been to WDW many times, I've read the stories here on the DIS over the years, and I have seen snakes and alligators while at Disney. Many have said it correctly, we are warned about not making ADR's 180 days out, making our FP+ at 60 days, logging in at 6:00 am on first available day and getting that BOG, CP (breakfast) or CRT ADR first, we all know about the Wishes Dessert Party now being $50 and no reserved tables anymore, we all know the FP+'s are no longer available for Wishes, we all know about the Jungle Book show and the failures so far of the ROL, we know just about all the ins and outs of WDW, but most of us not for a minute even put a single thought into an alligator or snake attack. In fact I'm willing to bet more people have been more concerned about getting the Zika virus while in WDW while the risk is very, very remote.
