My partner and I have reservations for September 22-26. We've got the "whole enchilada" (as some of us in Texas say) for this trip -- plane reservations, resort reservations (the Riviera), Park Hopper tickets, Boo Bash tickets, and yes, a private VIP tour. We are both fully vaccinated (in our 50s) with no unvaccinated children or family members in our home. We can and will happily wear high quality masks (KN95), eat outside or in our villa, and thanks to the combination of Boo Bash, VIP tour and the high likelihood of low crowds at the time of our visit, we should be able to avoid packed crowds and long waits for rides.
So we've looked at our personal "risk basket" and decided we're fine with going. Is there some risk? Yes. But I think from this point on, I'm going to have to choose to live with some risk from this virus -- my partner has to go to work outside of our home every day, my job requires me to be in the office or traveling for work regularly-- and I doubt COVID is going to simply disappear. I'm not willing to cut out all of the good and fun things in my life (like travel and Disney) to further lower my risk, and I'm not willing to rely on the idea that there will be some perfect day in the future when I can take this trip with little to no risk. (I thought we were at that place and then Delta came along.) Instead, I'll try to calibrate and balance and manage the risk to live the fullest life I can that's right for me.
But each of our "risk baskets" is very personal and very individual. Any one thing (like having an unvaccinated child at home, among many others) can tip the risk basket one way or the other. This is surely the perfect case of "your mileage may vary." I wish everyone only the best as you make these hard decisions.
