20 years old and wants to play B&M poker in Vegas

[AlfilRey]

Ok, so I'm 19 at the moment but over the summer a few 21 year old friends of mine are gonna go to play the Vegas live games for a few weeks, maybe a month.

I will be just turned 20, and look that age at best. Do you think it's worth my while to make the trip, in the hopes I won't get ID'd, or will I get kicked out of the casino too often?

Also, if I'm sitting down and they come over to ask me for ID, and I obviously tell them I don't have any, will they still allow me to cash out my chips?

Thx.

p.s. what about online poker? I know it's illegal in most of the US, or you can't deposit or whatever. Does that new legislation also apply to Vegas?
