I feel like I'm being unnecessarily harsh. I'm on a desktop, the design seems clear and clean. When I ask for an area I get a tiny cluster of flags that I then need to zoom in on, but I guess that would be easier on a mobile, just pinch/zoom. If I hover over a flag I get the details, but when I move to click on one of the links, they disappear, so I can't actually access the details. I can't phone to make a reservation, or check on the Google search results.

Those are my immediate usability comments.

Edit: These are of necessity "drive-by comments," neither crafted nor gestated. I'm in the middle of other stuff, and had some immediate thoughts. Take them as intended to be overall helpful. And now I need to go.
