Don't mind Mr. Mankie, like many of us on this message board, he has a built in keyboard function that sometimes only allows typing sarcasm. There's also one for irony but the sarcasm button is used more frequently. We forget to turn it off sometimes before typing.
The club is great, one of the best in the country. The Disturbed show will probably be packed, get there early if you want to find a good viewing spot. There is a large floor area in front of the stage and there is a second floor balcony level. And also a smaller third floor area, which offers a great view and sound, but you're farther away.
Many bars in the club, only 1 or 2 take credit cards, so bring cash if you drink (but there is an ATM on site).
If you're not familiar with the area, either take the Metro or pay in advance for parking (can do that via tickets.com) and you are guaranteed a parking spot no matter what time you arrive. For a sold out show, on-street parking will be tight.
The security staff is great; very professional. But, do not be an ass or try to do something illegal, they won't tolerate it. They will kick you out in a heartbeat (albeit in a professional manner).
If you want to drink, bring your I.D. Even if you look like you're 50 years old, no I.D., no drinks.
Have fun. Great venue.
