I am from vegas, .. vegas is expensive.. I was home for the weekend and dropped 1k gambling on non-poker games ( just having fun w/ my friends).. That being said, I play live NL there and in AC all the time, $100 is no where NEAR enough money to cover the swings @ a $50 or $100 table. That could be gone in two bad hands in a row. I would say you want at least 8-10 X the buyin to be comfortable for an extended trip, but thats just me. And if you plan on playing any house games (i played mostly carrib stud) plan on having a lot more. The minimum bets at most places are at least $10 + 1 progressive, I usually play the 10 or 20 tables, whether it be carib, bj, etc
