Yes. Robin, in terms of Delta from the perspective of the customer and the booking environment, I think I would say in the last 2 weeks, we've seen very positive growth in demand. As we moved through the spring with vaccinations and as we announced return to service and as customers saw our ships return, we really did enter into a very positive booking environment. And I think over the last 2 weeks, the positive environment continues, but it hasn't been at such a trajectory as it was. But it's really short term. When you look into '22, we see no material impact at all on the increases in bookings for '22. So I think customers, consumers now see this for what it is. It's a blip and a bump. I think we feel encouraged by the protocols that we've got in place, as Richard mentioned in his opening comments. We've been very encouraged to see that when we do have a positive COVID case onboard our ships, we very quickly contact trace, test. And what we find is that very often, you may have a COVID positive either from a vaccinated or unvaccinated guest, and they'll be in the very same room with somebody who's vaccinated and they test negative. So the vaccines are really working. I think our vaccination population, so to speak, as Richard mentioned, I think in the month of July, we -- our ship sailed with around 92% of the entire community vaccinated. And in the month of July, we were still accepting kids from the age of 12 to 16 who were vaccinated. And starting on August 1, that number has dropped down because our policy requires you to be vaccinated 12 and up. So I think the good news is, if there is good news with the Delta variant, is that people are becoming far more accustomed to this. If you've got a highly vaccinated population, there's minimal impact. And I think, increasingly, as our ships sail, as we encounter this, we communicate, we're very transparent. The feedback we get from our customers is recognition and relief that this is very contained and something that's going to pass.
