Visiting tourist going to the Boca Juniors basketball game tonight! Need a few tips

Hola everyone!

I’m a huge hoops fan visiting from New York, and before I wrap up my trip and fly out later this week, I really want to check out some LNB action. I'm planning to head down to La Bombonerita tonight for the game against Unión de Santa Fe, but I wanted to ask the locals for a little advice first:

1. Tickets: Is it safe to just show up and buy general admission at the boletería with cash tonight, or do these games usually sell out? Trying to avoid the hassle of online portals rejecting my foreign credit card if possible.

2. Timing: I see tip-off is at 8:30 PM. What time should I actually get there to grab a ticket, find a good spot, and soak in the pregame atmosphere?

3. What to wear: I already know the golden rule—absolutely no red and white! 😂 But other than that, anything I should avoid wearing, or is a standard t-shirt and jeans perfectly fine?

4. Getting home: I’ll be heading back to Palermo after the game. Since it'll be late, is it easy to grab an Uber/Cabify right outside the gym when the crowd lets out?

Any other tips for a first-timer at La Bombonerita would be awesome. Really excited to experience the atmosphere. Gracias!
