Waiting in line for the switch 2 (never done it before) any advice from veterans?

Never waited in line for a console release before and just thought I’d come here for some advice. Plan on going to a mall (In Brooklyn) that has a target, bestbuy, and GameStop. I know there will be people waiting the day before. But since I have work the day of the launch I won’t be able to be there. The current plan is to get there at 6-7am the (GameStop opens at 10) but I’m worried that even then I won’t be able to nab one. Anyone with more experience than I have some advice?
