For the longest time to competition was a click away. Now its a drag away. Google is providing the information you likely want, and your can still type in or use a bookmark to go to your favorite travel site.
Problem is that Google can easily bulldoze their way into any market just by creating their own service and then putting at the top as a widget. They did that with flights as you can see here and they were sued for it 8 years ago already, although I think that case is still active.
On the other hand I don't think it's OK to put limits on their creativity and efforts to improve user experience. If they want to make a topic specific widget, why not?
If you type 123+321 it will say 444 first, then display search results. That's how it should be, they don't have to protect the "123+321" keyword market.
