Not bad, but its WAY too over designed. The actual functional part on the front page is like a black bar that is 10% of the page. The start your adventure part is nice, but serves little functionality to me. Yes its cool to see all these awesome places, but I don't think I'll be going to Berlin anytime soon. The search page looks good still, just not a fan of the front page.

Compared to Kayak which makes it super obvious where to start, and the "Start Your Adventure" equivalent is top cities people travel to. That section should be a supplement not a main feature.

I don't know if I agree with this. People like to jump on some bandwagon that every social media is dying off. Its definitely changing, but dying? I don't think so.
