We went to a BAAF one that was for all the LA's in our consortium.
You turned up, went into a room where you were told what to do and given a book of profiles. Then we went into the hall and played with the children and their foster carers, although spent half the time hanging around on sidelines waiting to play tbh. Staff very friendly. Felt for the foster carers too as a bit of an unusual situation for them.
There were way more adopters than children and it did feel competitive which I didn't like at all. Kids seemed to be having a ball though and unless of school age, I don't think they really had a clue what was going on, other than lots of people to play with them.
It's interesting to read a child's profile and actually meet them because some are quite different and things that may concern you on paper, just drift away when you meet them and with others things I might not have been concerned with on paper, I realised I would actually struggle to deal with. We went to our first one before even been to panel, so post that with matching the experience really helped us know what we were now looking for in a written profile, that was useful, so even though matches we followed up on from that day never came to anything, it was worth it. The hardest part is that if you do feel you make a connection and then aren't chosen, that is worse than feeling like you made a connection just with a profile on paper, or a video. This happened to us and my DH particularly struggled and I'm the over emotional one! Despite having a successful match (the perfect match! ) since, through our own LA, where they approached us as normal, the memories and emotions of that day and follow up from the day have stuck with me and are some of the hardest parts of our journey, looking back.
BUT if we adopted again....Would I want to attend another? not really tbh. Would I attend another? Yes, definitely. Because I believe in what's meant to be is meant to be and if you don't seek, then you may never find. Just prepare yourself emotionally for the experience and plan nothing for rest of day, you will need a relaxing rest of day to process it all. Though some other days mentioned above sound better!
If that sounds a bit too brutally honest and not too positive, sorry! I've read other stories where people have found their match and rate it as best experience ever and others who've gone and thought not much about it, having found no potential matches, so for you the experience maybe a very different one.
