Horribly broken url management.... selecting a city replaces the home page in history so you can't use the browser back button.<p>Plus the search recommends locations nowhere close to the search term... and has like 15 total destinations.
In addition to being costly it also gets very crowded. Went to Amsterdam and couldn't see the Anne frank museum due to a huge line of tourist. Then went to italy's main square, couldn't get inside the Basilica. Then we went to Louvre, same thing. I just don't have patience to stand in line for hours, so it is kind of my fault. Still, I think it's best to avoid the main tourist attractions because they are generally all booked by tour operators and each groups now contains hundreds of tourists.
I have a similar idea (currently on the backburner) but instead of focusing on "peak" season I thought you would define your own criteria. Some examples:<p>1. When is a good time to visit (ski resort) based on your chances of catching a powder day? What about a sunny day? What about no lines? What about all 3?<p>2. When is the best time to visit northern Thailand when it's not too hot.. but air quality is still decent (ie not peak "burning season")?<p>3. When is a good time to visit San Francisco if I'm into music (perhaps during a festival) but I can't stand rain? And how does that correlate to hotel pricing?<p>Etc..
