booking ke upar thoughts

q1 2018

let me pick up on a couple of your opening question then maybe add a comment about Q2

as well. On the booking window, we did continue to see a modest decline in the booking window.

We noted that we started over the last few quarters to see a modest decline. We think it's likely

impacted by some of the things we're doing around our optimization efforts in the performance

marketing channels. Without going into all the details, we are targeting a less lower converting

and less upper funnel ad placements that's having an impact on the booking window.
