If I had the money and enjoyed the theming, absolutely. As it stands, we leave in a few weeks for the Boardwalk, also on a Disney waterway. Will we be on the beaches at night? Nope, we never were, and I suspect they'll be closed at night for the forseeable future.
This is not a "Grand Floridian" issues. It's not a "Disney" issue. It's a "Florida issue."
The gator didn't target that family or the Grand Floridian or Disney. WDW was built on swampland in Florida, the gator's natural habitat.
That heart-wrenching tragedy could as likely have happened at any other WDW resort, or at any part of Florida remotely near water. Or at any other location anywhere near the Gulf Coast. Just as a family vacationing in LA may have to face the remote possibility of an earthquake, or a family vacationing in the Midwest may have to fact the remote possibility of a tornado, or a family vacationing on Long Island or NJ may have to face the remote possibility of a shark encounter, or a family enjoying a mountain vacation may have to face the remote possibility of a bear encounter, a family vacationing in the southeast may have to face the remote possibility of an encounter with an alligator.
Yes, of course I'll be more attuned to the alligator issue than I was a week ago, just as I'm more attuned to airline safety after 9/11. And obviously Disney and Universal and every single other tourist attraction and college in gator territory will now be much more attuned to the same issue.
But we'll be in WDW at the Boardwalk in a few weeks.
