Nothing major. I recall the search page was different. Instead of "dropping down" when you click "find and reserve", it was more on the left side of the screen. The layout just looked different. I only saw it the one time, just checked now and back to regular.

I am sure they are tinkering around with it, maybe doing usability testing or something. I am sure it is taking a lot of time and money, and will end up being worse for the user. Just always happens that way.
