Habrovtsi collection - who goes to JavaOne and / or App Developer Days (2011)?

I propose in this thread to unsubscribe to those who are going to some (or both) of these two conferences, so that if you wish, you can somehow cooperate with those who are traveling from the same city, plan to live in a particular hotel, etc.

The first is JavaOne (http://www.oracle.com/ru/javaonedevelop/index.html), April 12-13, 2011, in Moscow.
The second is Application Developer Days (http://addconf.ru/), April 29-30, 2011, in St. Petersburg.
