Not cancelling, but will be playing it VERY safe. Resort is paid in full and nonrefundable, so I'm going, no matter what. No indoor dining. KN95 or N95 mask at all times outside of my room. Most meals I'll make and eat at my resort (I'll have a kitchen.) If I eat out, it'll be outdoors, well away from others. Mask on in corrals and probably much of the races: anywhere I can't be comfortably away from other people's breath. Very little socializing, and only outdoors and masked. Limiting my indoor time to short rides, quick stops in stores. No public transportation.
I'm at high risk for complications form respiratory illness, so honestly, this is how I've lived my life the past 2 years. I've been to WDW multiple times during that time, and this is just my new normal now. I'm only 100 miles from WDW, so I don't have to worry about the travel part, which makes it all easier.
