Love this website about yacht and boats. It's in Russian, but I used automatic translation and found some useful things about marine navigation, sailing, and some places to visit by boat in Europe.
Very good for yachting fans!
I like to use Expedia for booking tickets and hotels in US, usually they give best price. For European cities and, especially, Eastern Europe they are not so cool, and you'll can find better offers on other websites!
Tried to find nearest shopping malls and found this site. Malls.Com looking good, but not enough info for shoppers this time. They have to publish more info about deals and sales in malls, instead of corporate news and retail space offers
