Also please, where in Hobart please. Thank you :)
Again, davemurray101 would be the person to speak to. I'm not sure if you've ever visited Hobart but it's really not a big city. The CBD area is really quite compact.
Like you, I don't have any real information but I'm assuming most events will be in/near the CBD (pretty much all the Australian Uncons I've attended in the past have followed this pattern). I've gone ahead and booked accommodation in the CBD on this basis. Basically, any accommodation in the CBD will not be far from the action.
If, for some reason, the Uncon doesn't go ahead on the planned dates in November 2018, I have to admit I'm not particularly worried. I would have taken a short holiday at roughly that time of the year anyway, and my Hobart holiday will be going ahead, irregardless of a BC Uncon.
I understand the circumstances may be different for people who have further to travel.
