Hi Charlotte,
We're all kind of hibernating (in the Summer...) before the registration begins. That's why it is awfully quiet here.
If you are on Twitter you may want to follow
https://twitter.com/GABITEvents there, as they have all the news regarding when registration opens etc.
The event itself usually has around 270 attendees plus staff and stewards.
Amanda does two Q&A sessions each on Saturday and Sunday. The photo shoot with Amanda is on Saturday, the autograph session is on Sunday.
Saturday also has an auction where the money raised goes to Sanctuary for Kids and Hearing Dogs. Even if you don't want to bid in the auction it is great fun to watch Amanda trying to up the bids.

In between Q&As most of the attendees spend time in the hotel lobby. It's a great way to meet new people.
Gabit also does a Meet & Greet for the new attendees on Friday.
BTW, there are usually a lot of fans from France at the event.
If you have any questions, just ask.
