Management
Yeah, so the – I think, we're off to a good start on the integration, but I think, we are by no means declaring victory today. We've got a lot of work ahead of us. I think, the team is performing extraordinarily well in getting at that work, and they're incredibly energized by what has been accomplished and what we have to accomplish, and what we think we can achieve by accomplishing it. There are plenty of risks around. I think, if you identify one it's going to be around technology. And we are – you know, it takes longer, it costs more than any of us would like, and I don't think that's unique to Marriott or unique to the hotel business. I think, when you look across the corporate landscape, it is what we see in company after company. And we've got to make sure that we are moving as quickly as we possibly can, because these technology platforms will really allow us to drive, particularly the kind of revenue lift that we think is available, by having one reservations platform and one loyalty platform. And of course, secondarily also allow us to deliver these technology platforms at lower costs to our owners, because we'll be supporting one and not two. And even as we pull those platforms together and do all those things, we want to make sure that we are continuing to innovate and do the kind of new things that our customers expect us to do. So a recent example of that is our investment in PlacePass which is really an online or virtual concierge which helps our customers plan for their trips before going. It's a space that we're very excited about, but we want to make sure our technology platforms allow that to be linked to our loyalty sites and our dotcom sites so that we can drive that business even as we do that and other integration work. So long way of saying technology would be probably the thing that we are maybe most, what, frustrated by the cost, and time associated with it, maybe most fearful about it, but also most convinced that it will drive upside long-term to the performance of the portfolio.
Bill A. Crow - Raymond James & Associates, Inc.: That's helpful. And then if, as an industry leader, I was wondering if you could give us some comments on a couple of headlines that are out there. The first one is the industry's efforts to lobby Congress regarding Expedia and Priceline. The second one is kind of this airline overbooking news and whether you guys have considered whether you need to make changes to your booking patterns, or, you know, to take away the risk of walk-in guests.
