I've only attended 3 events so far, and from what I've noticed, they are centered around casinos. I'm not sure if that is the standard or pure coincidence, but if it is a "requirement," that significantly reduces the locations on the east coast. Being from Jersey, I could recommend Atlantic City and Foxwoods (Connecticut), but those are very popular venues and I'm sure that they are tons of offers that will conflict. Maybe Chicago?

Why does everyone try to make it harder than it really is? Overthinking makes the game that much more difficult.
