I don't personally think we're going to reach herd immunity (which, contrary to your subsequent post, isn't something that can just be redefined if we don't get to the threshold the science indicates we need), or if we do, it will take another year or more and vaccines becoming available to all ages. So the question to me is how we move on without it, or at the most optimistic, how we move on while we're still trying to get there. Masks are a good tool that have no measurable downside other than minor discomfort. If the question is more ordinary living with masks or continued distancing and capacity restrictions without, I don't understand why anyone would choose the latter... though I guess people who just don't care about festivals and fairs and concerts and live arts might see the minor discomfort of a mask as being worth losing those things over.
I think the more reasonable question would be no kids under 12. Most of the analysis I've read seems to expect Pfizer to get approval for 12 to 15yos next month, and since the only unvaccinated member of my household is in that age group, I have been following the buzz/rumor/projection around the issue fairly closely. With a little luck, we might even be able to get DD12 vaccinated before we head off to Alaska this summer (though that's certainly not something I'm counting on, of course).
And as far as what a
Disney cruise looks like with no kids under 12? I don't know, but that might be enough to convince me to try one for the first time to find out!

But when most of us talk about summer lowering case rates, we're not talking about the direct effect of sunlight but rather about the seasonality that happens due to the virus spreading far more easily/efficiently in indoor settings and places with poor ventilation. A dinner party in my dining room with 8 guests is much riskier than a dinner party around my patio table with the same group. Dining inside a restaurant is much riskier than dining on the same restaurant's deck. Those things do give covid a seasonality based on human behavior, and since most of this country has weather more conducive to outdoor activity in the summer, that makes summer an ally of sorts in trying to limit spread.
