Going on my first ever trip to Vegas, and plan on really testing my counting endurance. And would really like to bank some $$. What is the best places to hit up?
While this might not be as specific of an advice as you're looking for, I suggest that you go play everywhere. You'll run out of energy and time before you get to play everywhere. But there is no better learning experience than playing everywhere. If you succeed at one place, figure out why you succeeded. If you didn't succeed, analyze, make sure you didn't make a mistake. If you get kicked out another place, figure out why, apply it to the next place. Where ever you didn't play, there's always the next trip. Use some risk-adverse plays if you're just starting out. Have fun. Don't let the heat get you down. Keep moving, and they won't be able to catch you. Probably. Hopefully.
Added advice. Older, experienced players sometimes regret their indiscretions when they were younger, less experienced. Try not to do anything that you'll regret later.
$$ is what you might be after now. Longevity is what you might be after later.
