Sure. I'll start, and maybe I can pass Sourav chime in as well. For the second half of 2021 we have 1 million room nights on the books. And we have, at our Marriott managed properties, we booked 144,000 new room nights this year for 2Q for the second quarter through the fourth quarter of the year. Of those 144,000 new room nights, about 70% of those were for the second half of the year. So that 1 million room nights that we have on the books for the second half of 2021 equates to 50% of the room nights we had in 2019, same time in 2019. So the split between the bookings is really leaning fourth quarter a little bit, not a lot, call it, 54% in the fourth quarter. And the other thing I'd like to add is that we have a high degree of confidence that those groups are going to show up because our managers have just scrubbed all the bookings and to make certain that people aren't just hanging in there are going to cancel at some point in time. So it's not great, but it's good. The fact that 1 million room nights are still there and holding up is encouraging. As we look out to 2022, it is -- we have what about 2 million room nights on the books in 2022 Sourav, I think, something like that? And it is very dependent at this point in time on when restrictions are going to be lifted in key markets. To just put some back around it, some of the markets in Chicago, I think, just announced yesterday, when they're going to reopen. California is expecting to fully reopen on June 15, Boston, August 1, New York, July 1. And I think that as markets reopen, that's the first thing that has to happen. But more importantly, what has to happen for the business transient traveler to return. And the -- in groups to start booking into next year in a more meaningful way is we have to continue to get the pace of vaccines out there, get to herd immunity in the country and very importantly, get our children back-to-school. And I think that we're hopeful that, that's all going to happen comes to September. I don't know, Sourav, do you have anything you want to add on this point?
