Miners Ball Fur Rondy

So someone told me I had to go to this Miners Ball during Fur Rondy. I was planning on leaving the 3rs or the 5th but this looks like something I may love.

However I have 3 concerns...…

#1 Which one? 2 come up on google same day and time but listing 2 different convention centers.

#2 says costume... Like Mardi Gras, Halloween? Somewhere I read dress up like the theme of this years Fur Rondy but could not find out what that theme was.

#3 I need a date for this. Male or Female NON SMOKER IS A MUST. I can not stand the smell of it just ruins my fun time. I deal with it when I have to but not on my own personal time. And fit enough to walk with out a chair and be active in the activities. If you need an electric cart to shop at the store then you will not be able to walk around this huge event and boogie with me.

HELP I want to ENJOY THIS!
I loved Alaska so much I had to come back for this winter fair
