Robin, there's a lot in your question. I think the conversation around negotiating with ports and local authorities, depending on the specificity and the criteria involved in all that, we do that meaningfully. For example, we've sailed overseas -- the industry has sailed, I think, almost 400,000 guests so far overseas. And to do that, we have to have arrangements with all those places and destinations we go. And so that unto itself, depending again on the criteria established and the paperwork involved that may not be so burdensome because we need to have an understanding. Keep in mind when all this started, people were concerned about ICU units being overwhelmed and so on. And fortunately, that hasn't happened with the advent of vaccines, with the advancement in treatments, with more rapid testing, more readily available testing, with all of that, it appears well in a trend and a trajectory where that is no longer at a big risk. Having said that, of course, we want to be having a prearranged agreement with what are we going to do if there's a case onboard? Because if it's in the community, there's a chance of it being onboard. The specific solutions you're referring to in terms of everybody vaccinated and so on and so forth, we'll have to see how that evolves. We continue to be informed by global medical and science experts. Of course, we're going to be in compliance with whatever the protocols are regulated wherever we go. Of course, we're going to do that. But as you know, today, everybody doesn't have access to vaccines. Children are not yet really eligible for vaccines. Hopefully, that'll change over time. Hopefully, the availability of the vaccine so everyone will have access will also change over time. And we would encourage everyone to be vaccinated. We would. Today, we can't buy vaccines to do anything. So we just have to let this play out. And keep in mind, we are currently sailing without any major incident, without anybody being vaccinated and with protocols in place. And so you're hoping that the combination will result in -- the combination of vaccinations and other protocols will result in a situation where the public health interest is being served, and we don't have to go through a very burdensome and almost unworkable situation. The key thing is mitigating risk. We can't be -- prefer not to be -- hopefully won't be asked to stand up to a zero risk standard because, frankly, nowhere else in society is that being considered. We just like to be treated similar to the rest of travel and entertainment and tourism sector. And so if we do that, we'll be fine. An interesting point is today, you can fly out of the U.S. Today, you can fly out of U.S., take a cruise and fly back into the U.S., whether you're vaccinated or not. And today, if you're vaccinated, you can't take a cruise ship from the U.S. And so we've got a little work to do here, but we stand with the CDC. We stand with the administration and working together to come up with practical solutions that protect the public health but allow 0.5 million plus people in the U.S. that are dependent on the cruise industry for jobs to be able to get back to work and give people the vacation experience of their choice. Thank you.
