I think you find Lubricus to be quite a bit different than Ascendio. I haven't been to Ascendio, but I have been to other bigger cons (as well as to Azkatraz back in 2009, which is where I first met all the Snarry fen).
The small nature of it is what makes it so much fun. Not crowded, personable and with so much fewer people you get comfortable so much more quickly. It's quite easy to strike up conversations, and the panels are really VERY fun to attend. My favorite last year was the Drarry vs. Snarry, where the moderator gave each group their own flip pad on an easel and a big marker and our own side of the room, and we had to write down why our pairing worked so much better and what their tagline should be. I can give you the link to the writeup for that panel (which is really fun to read) if you'd like.
I just know you'll have a GREAT time. I really look forward to meeting you!
