Yes, thanks for those questions. In terms of marketing strategy change, no, the marketing strategy, very similar to what we have done in 2018. Remember that 2017 was the year that we started to do TV. We started to do that in June. 2018, we stepped up the level of investment in TV because we had a full year of spending, spent about $115 million. And as we look into the next year, we feel we have the appropriate level of brand advertising now and so we're going to be spending roughly the same amount. We're happy with what TV has done for us and how brand marketing can perform for TripAdvisor and so we're going to continue with that. As said in our prepared remarks, and as evidenced in the fourth quarter, if you watched our TV spots, we are diversifying the message from just this pure focus on hotel to the broader value prop for TripAdvisor but a similar level of overall spend. In terms of the performance marketing, on the hotel side, continuation of our strategy for 2018 into 2019, we have reduced marketing and have achieved much higher efficiency. That's been the driver of our profitability last year. We drove 27% EBITDA growth last year. And our marketing optimizations in hotel were a big factor of that. And so, see that continuing. Obviously, the biggest impact is going to be in half one because we're going to be lapping into the biggest changes in the second half. For Non-Hotel, as Steve was just describing, we're leaning in on Non-Hotel. It's a high-growing category for experiences and restaurants. And obviously, we're going to capitalize on that. So there, we're leaning in more on marketing. So that's our overall approach. It's not too different from what we've been doing in 2018. In terms of meaningful investments in Non-Hotel, yes, read the script for this. We're investing in both experiences and restaurants. And as we said in our prepared remarks, we're investing in product. We're investing in supply. We're investing in marketing. We're really investing across the platform. We have a large still – large opportunity ahead of us with experiences and restaurants. If we look at international opportunities, if we look at just the supply, we can – so again, if you look at how much of the experiences business is still offline, we have a huge opportunity. And so we're making investments so we can capitalize that for the future.
