I bolded the obvious key words there. If you're legal, Vegas is there for the taking and you'll never see better customer service. However, if you're not "of age" you're reminded constantly reminded that you're not going to be catered to. As someone who doesn't have children of my own, and plans on keeping that way, it's why I prefer Vegas. That bold strip of carpet running down the middle of the casino isn't there for looks. It's there to let you know your boundaries if you're under 21. Places like Wynn won't even allow strollers ^ We're talking about hotels that are publicly traded and can't afford to cut anyone a break. When I was 21 I had a baby face (still kinda do) and was carded for just about everything. I wouldn't bet on being able to charm your way through a check-in if you're underage. People like their jobs.
