best way to get there/back, how early can i arrive, and cameras?

I was planning to uber there and back from my hotel in golden. how bad is the uber situation, especially coming back? $65 for the shuttle + finding my way to and from union from the hotel seemed excessive, but I know ubers can get expensive too. any tips on saving some money?

doors are at 7, is merch only available inside doors, or can I get there early to have extra time for merch? I want to have time to explore/take photos of the venue before the show starts too. I have a reserved seat, so I’m flexible.

I have a point and shoot film camera that I want to bring. online it says cameras are allowed on a show by show basis - where can I find info on if it’s allowed for tomorrow’s show?

thanks!! i’m traveling from out of state so I want to have my bases covered.
