Tell her to belly up to the table & begin playing.
If you want to educate her on 6/5, splits, surrender & all that jazz - you can. It's your choice.
No, i dont think a casino would let her play early. Only exception would be is if she did NOT get carded.
As for coyote ugly?? I thought that was a bar/nightclub?? Not sure what it has to do with her blackjack virginity.
Good luck folks.
