Google saw a tremendous 50 percent increase in travel questions on mobile phones last year, so it's only logical they came up with Destinations, a new set of functionality for Google mobile search that accommodates your vacation needs.
It works as simply as you could hope for: search something like "europe vacation" and various travel destinations in Europe will pop up, complete with pictures, and dates and prices for flights and hotels. If you want to get more specific, quick tabs let you change dates, travelers, interests, and your budget. And if you're thinking long-term, you can compare prices across the next six months. Finally, the Explore tab lets you see what the weather is like year-round wherever it is you're thinking about going.
With any luck, Destinations will expand beyond mobile before too long.
