Tim - thanks for the feedback.
I trust you noticed the X in the top right corner to close a bubble? Still, we know that the behavior is not perfect. What we're not sure of is, what the ideal behavior would be given that some people like to mouse over a lot of hotels in a very small radius while others search large suburban area with very few hotels per mile.
The problem with having it disappear when you move past is that we don't know if you are moving the mouse up and around to one of the links in the bubble.
What we could do is revert to the original behavior where you need to click on the hotel icon to see the info and then hit the X that is in the top right to close it and select another (or just click on another icon which will simultaneously close the 1st and open the new one).
Thoughts?
