First of all, welcome to the boards, and let me add you made a fine decision for your next LAN event.
1) I reckon such good competition (15th on an ED ladder is pretty good) will be healthy for our returning heroes!
2) There is always a possibility that any game will feature as an official tournament. We base our decisions on what tournaments to run almost entirely on our attendee preferences. You should have a 'Profile' link on the top left box on the screen. In there, you can tell us what games you own and order them by your preference. The more popular games emerge as favourites - a list we'll look to for inspiration when inventing the main events!

3) There is no bar. Food and drink can be bought very nearby in the village centre. A rather large Co-Op is about 15 mns by foot and two minutes by car. There are regular runs to the village so expect plenty of opportunity to tag along.
4) There's a room upstairs reserved for sleeping, though be aware that we have some heavy snorers attending! So bring some earmuffs too. There is ground outside for pitching tents too, which will offer you greater privacy, space, and quiet.
5) I think almost everyone is very friendly. Look to the testimonials in the previous events' forums.

It helps that we are a 40 player-max LAN.
