SALH: I completed my Stage 2 in November (I think) and was offered just a single Stage 3 slot for Prestwick, which I didn't want to take. So since then, I've just been rechecking the link that I was sent, and the new dates were listed there.
There was one earlier date, but it was at the Bournemouth centre, so I opted for Swanwick, as I have stayed in a nice hotel for the past two stages.
I'd recommend the 31st March so you can see me ;D haha!
