Posted this on the WDW subreddit but I feel like it would be helpful to post here as well -
IANAD - but going in 11 days and trying to separate truth from media hype.
Put it this way, if you feel like its not worth the risk, you are immune compromised or have health issues that would make getting the virus a serious issue then I would definitely consider moving your trip to a point in the future where we are somewhat in the clear.
Knowing that the virus is in Florida and has signs of community spread does feel a little too close for comfort. Additionally, the virus itself is scary because we don't know that much about it, but what we do know so far is promising in that its not going to have an insane mortality rate and people of good to average health will pull through pretty well if they do manage to catch it.
So these are my thoughts with going in the next few days... be vigilant and prepared. Wash your hands before eating, sanitize after every ride, bring disinfectant towelettes (wet ones, clorox etc) for ride vehicles, tables, really any surface you don't feel comfortable touching. Don't touch your face and if you have to sneeze, cough, etc do it into your elbow or even better a napkin or towel. And most of all.. if you feel sick or begin to feel sick, do not go to the parks!
There's no need to live in fear, just a need to be mindful of your surroundings and others. Again, its up to each individual/family to mitigate and choose their own risks, but no need to fear monger or try and scare the magic out of others vacations!
Have a magical day - and to those who will be braving the parks with me in the next few weeks, to infinity and beyond!
PS:
Disneyland is putting handsanitizers in all QS locations, which means Disney World should be following suit in the next few days.
