 Yeah, there are cancellations that can happen, but the vast majority of that is going to come through ultimately in revenues. So that's a bit of a forward indicator of how we're doing. And that increase is really a combination of increased pricing, us elongating the booking curve, so taking bookings even farther out than we had even just a year ago. And we're doing a better job of bundling our offerings so that people can spend in advance of the cruise, not just for the ticket price, but certain onboard experiences.
