If you are free on the weekend of the 21st and 22nd and are anywhere near Cambridge (the UK one!) then make your way to the Drupal Science Camp. The details on their website are a little sparse so far, but it's shaping up to be an interesting little event - plus ComputerMinds are sponsoring it, so it's got to be good :)
Tickets are a measly £10 each, and it looks like there is some deal with the local Travelodge with rooms available at £15 each - it's a bargain not to be missed ...
More details and sign up info can be found here :
See you there :)
