Does the flea market still work as it did a few years ago? Show up extremely early to set up stuff. Man comes around during flea market to take money? There are some reserved spots, but still areas open to one-timers?

Yes it does.

Yes indeed. Nothing has changed here that way. The owner Toby Aka "the rent collector" will come around and collected the vendor fee/ rent.

Yes

Yes sure does

Yea on holidays need to be here by 5am

Yes, comes around 9 to make sure you had time to make your rent, which is easy on a bad day.
