No line or hassle to enter a Vegas casino (especially at noon on a weekday). It's a certainty you'll be carded at the blackjack table. It's also a near-certainty you'll do something to reveal what a noob you are, but who cares?
Recommend you spend a LONG time REALLY studying and memorizing blackjack basic strategy, for example by using practice drill software, BEFORE you whip out those dollars.
