The toughest part about December 31 this year? Trying to pick among these potential destinations ...
Christina Aguilera (Zappos Theater, 10 p.m.) Whether you're there for Stripped, Back to Basics, Liberation or all of the above, the pop star's Xperience residency has you covered.
America's Party Downtown (Fremont Street Experience, 6 p.m.) Go big with FSE's annual outdoor blowout, featuring live acts like Empire Records and Zowie Bowie and the debut of an upgraded Viva Vision canopy.
The Chainsmokers (XS, 8 p.m.) Andrew Taggart and Alex Pall teamed with Kygo for latest single "Family," and its video chronicles filmographer Rory Kramer opening up about his mental health issues. It ends with the message "Checking up on your friends is cool," strong advice heading into 2020.
Forever Young '80s Prom (Sparrow & Wolf, 10 p.m.) Channel your inner Pretty in Pink and indulge in passed bites from Chef Brian Howard, live entertainment, a costume contest and a champagne toast at midnight.
Future (Drai's, 10:30 p.m.) Pitchfork recently credited the Atlanta rapper with "rewriting rap in his own image." Hear for yourself at the Cromwell club.
Golden Knights vs. Ducks (T-Mobile Arena, noon) OK, it's not technically a New Year's Eve event if it's over by sundown. But seeing a VGK win 2019 sounds like a pretty sweet way to end 2019, plus you'll have time for dinner, a concert or a club (or maybe all three).
Guy Gerber (Encore Beach Club, 10 p.m.) The Israeli producer has underground accolades and big-name chops. He's worked with Puff Daddy and launched a left-of-center house party in Ibiza, and now he's ringing in 2020 with Kaz James at EBC.
Journey (The Colosseum, 8 p.m.) "Wheel in the Sky." "Don't Stop Believin'." "Lovin', Touchin', Squeezin'." "Any Way You Want It." "Lights." You know the songs. Go sing them.
Lady Gaga (Park Theater, 8 p.m.) The Strip resident presses pause on her primary residency (Enigma) for a more formal Jazz & Piano gig, appropriate on a night made for dressing up and drinking champagne.
Lizzo (The Chelsea, 9 p.m.) The "Truth Hurts" singer has had quite a year, highlighted by album Cuz I Love You and a role in Hustlers. If anyone can ring in the new decade with positivity, style and fun, it's this Minneapolis queen.
Maroon 5 (Mandalay Bay Events Center, 8 p.m.) Move like Jagger when Adam Levine and his mates renew their annual tradition of ending the year on a Las Vegas stage.
Mustard (Marquee, 9 p.m.) Dijon Isaiah McFarlane has worked with everyone from Tyga to 2 Chainz and Young Jeezy. The Rocnation artist and Marquee resident sends out 2019 the way he knows best: Vegas-style.
Nas (Tao, 9 p.m.) If hip-hop's your jam, it's tough to find a better résumé among NYE contenders than this Illmatic rapper, who has 10 Top 10 albums to his credit.
Ozuna (Pearl Concert Theater, 11 p.m.) He's regarded as the "New King of Reggaeton," and his latest single, "Eres Top" features another hip-hop monarch, with Diddy's "I Need a Girl (Pt. 2)" sampled heavily throughout. Hear it live when Ozuna plays the Pearl on NYE.
Samantha Ronson (On the Record, 9 p.m.) The English DJ recently played a celebration hosted by the Tegan and Sara Foundation, which fights for "economic justice, health and representation" for LGBT+ girls, women and allies.
Stick Figure (Brooklyn Bowl, 8 p.m.) Brooklyn Bowl has become the hub for reggae in Vegas, and this Northern California group—whose August album debuted atop Billboard's reggae chart—is a strong choice for a NYE blowout.
Taco Tuesday 2020 (Downtown Grand, 5 p.m.) What better way to celebrate NYE than with all-you-can-eat tacos? Enjoy gourmet grub prepared by Freedom Beat chef Scott Commings, tequila tastings, entertainment and more.
