Personally, I think that if you're in generally decent health and willing to spend a day and a half right now in close quarters for a luxury experience that relies on personal contact, you might as well freeball in terms of masks. If COVID is there, you're getting it either way, and the impact of the masks on immersion is just too high for the price.
On the other hand, I hope no one had this as their Make a Wish trip... yeesh. (That and the kind of people who are paying for the trip may be mad that money doesn't keep away COVID--"I paid this much and a dirty virus got in!"--even if they don't get particularly sick.)
