If it rains and you had outside seats, you're out of luck.

I think it's worth it to buy regular tickets, but paying extra to have access to the bar/bathrooms right there might be worth it.

I had fun when I went, but there was a huge thunderstorm/downpours, and I can't imagine wanting to run out in the lightning vs. peeing my pant.

If you want expensive, ask about a season pass to gain access to the top floor. That shit is bonkers.
