Sounds nice, but not possible when you are an experienced AP. When I walk into a casino especially in an unfamiliar venue I can never be sure what I'm going to see there, therefore I can never be sure what I'm going to do. Ever see a dealer paying 3:2 on Blackjack Switch? Not something I planned on, but I stayed until the end of her shift and missed dinner.
You don't know that. A marathon session in Las Vegas can have you in any store for no longer than an hour. I also recommend getting sleep just because its unhealthy not to, but only you know if you can still play without sleep.
