Next session there is March. There’s a session near my house in february with availability, but that’s a Sunday – can’t guarantee what I’ll be doing next weekend much less two months from now
Just book it and if you’re still unsure a week or 2 ahead cancel, they’ll still fill the slot.
I’m wondering what the “shambolic” people are experiencing. I’m in and out in less than an hour. If it’s actually disorganised rather than you just having to wait a bit it’s a matter for concern. It’s a well-tried system and will based on common procedures. Having said that, it’s scheduled quite tightly and I can see a couple of fainters on the chairs having a big knock on effect on throughput especially if it happens early in the session.
