Ultimately it comes down to free will and choice and responsibility. No one is making you go. Going anywhere at any time, one accepts some level of risk.
If everyone is wearing a mask, that’s a good start (and surprising to me, the parks have managed to maintain full compliance.). There will be distancing measures in place, but at times, you will have to be a responsible adult and manage to keep distance
Obviously, there are some folks who have determined there are enough measures in place to mitigate the “risk” of going to a theme park. Universal has decided that they will accommodate these people. If you get sick from going to HHN, that’s a consequence of a choice you made.
I honestly think mountains are being made out of mole hills here. Capacity will be reduced through UO policy and by the nature of what’s happening in the world. The majority of the folks at HHN will be people who “get it” and less of the “casuals” we’ve become accustomed to. I’ve seen enough from Universal over the past month to trust them to do this right.
