Las Vegas Strip

The Las Vegas Strip is the quintessential adult playground - and while it does have a number of family-friendly attractions (such as traveling art exhibits and world-class shows) - the “Sin City” definitely skews as being more adult-friendly with its heavy doses of flashy casinos and extravagant bars, restaurants, and nightclubs. For my money, I think your best bet is taking a leisurely stroll down the strip (from Mandalay Bay to Encore at Wynn is ~3 miles), popping into casinos and attractions along the way. Be sure to get up close for a production of the Bellagio Fountain Show, grab a drink (really, go for the views) in the Skybar at the Waldorf, and head to Treasure Island to scratch your blackjack itch (it offers the best odds/rules/bang-for-your-buck on the strip).
