Okay. Yes, I'll take at least start both those and Matt can chime in where need to. So on the Viator brand spend, I think we're looking at this as a very, on a very disciplined basis. And we look at brand spend across a lot of different dimensions very much kind of at the micro and macro level. At a macro level, we clearly are investing to drive awareness. And that is, we're constantly measuring that, right. And those are things you can do through unaided and aided brand awareness surveys, which we do. We like what those metrics are telling us. From the more of a micro level and thinking about effectives of brand spend, we look at a lot of different metrics because brand spend is an investment today that does help future periods, right. And we should see over time, improved conversion rates, which we're seeing. We should be seeing increased brand SEO or brand searches which we've seen. So there are a lot of different metrics which we use to evaluate effectiveness of the brand spend. And we use all these tools at our disposal to do this, because we do recognize brand spend is tricky. So, again, along those dimensions, we continue to like what we see and we'll continue to deploy brand spend. Again, we started this in the second half of last year. We are expecting to continue to campaign this year based on, again, what we're seeing there. The second question, which is around long term margin, our long term margin or I guess your question was really more on when to expect profitability. I would say last year we were profitable in the kind of the second half of the year or the third quarter of the year. And as we said, just to reiterate some of the points we made in our call in February, as we think about this brand, first and foremost, we think it's a great opportunity for us and a huge market. And we do think that scale matters, as I said earlier. And we'll continue to look at customer acquisition to build a very large repeat customer base. And that is what scale will ultimately drive very profitable business for us. And we do think that this business should have very healthy long term margins when we achieve scale. I think what's going to dictate that is as long as we continue to see healthy unit economics and we've already reviewed all the things we look at these around that. We're going to continue to kind of invest in that area, but we're going to manage it with a line of sight towards profitability. And as we said in our call in February, we're expecting the Viator margin to be approximately flat. And I think that aligns with how we're managing this, which we think is again, capturing customers with the proper unit economics, but then also having an eye towards that profitability level.
