The best family shows in Las Vegas are Tournament of Kings at Excalibur, Blue Man Group at Luxor, Popovich Comedy Pet Theater at Planet Hollywood, Tape Face at MGM Grand and BattleBots Destruct-A-Thon behind Horseshoe Las Vegas. Kids get in to all five. Two of them don't use a single spoken word, which is why a six-year-old and a grandparent laugh at the same moment.
Tournament of Kings at Excalibur
Tournament of Kings is the most complete family night on this list: a medieval dinner show where the meal arrives without forks, knights joust on horseback a few rows from the tables, and every section of the arena is handed a kingdom to cheer for. Kids who love knights and horses get the loudest night of the trip. Adults get dinner and a rare excuse to shout for a stranger on a horse. Our Tournament of Kings guide walks through the night course by course.

Where: King Arthur's Arena, Excalibur, south Strip. Length: 90 minutes, dinner included. Ages: all ages. Best for: one big night out with dinner built in.

Blue Man Group at Luxor
Blue Man Group works for every age because nobody on stage says a word. Three bald, blue performers build the whole show out of drums, paint, PVC pipes and flying marshmallows, and the crowd ends up part of it. No joke needs adult context. The percussion is loud, and that's half the thrill.

Where: Blue Man Theater, Luxor, south Strip. Length: 90 minutes. Ages: all ages, three and up recommended. Best for: mixed ages with no shared language.
Popovich Comedy Pet Theater at Planet Hollywood
Popovich Comedy Pet Theater puts Gregory Popovich on stage with cats and dogs rescued from shelters, and they steal it from him. Dogs jump rope. Cats push strollers. Popovich fills the gaps with circus juggling and slapstick. At 60 minutes in the afternoon, it's the right length and the right hour for the youngest kids in the group.

Where: V Theater, Miracle Mile Shops at Planet Hollywood, center Strip. Length: 60 minutes. Ages: all ages. Best for: the youngest kids and animal lovers.

Tape Face at MGM Grand
Tape Face is New Zealand comic Sam Wills, who reached the finals of America's Got Talent in 2016 with his mouth taped shut. He still doesn't speak. Every joke comes through props, music and volunteers pulled from the audience, so a child catches it at the same instant as the adults. No two nights match. The volunteers make sure of that.

Where: The Underground Theater, MGM Grand, south Strip. Length: 90 minutes. Ages: all ages, under 18 with an adult. Best for: families who want to laugh at the same thing.
BattleBots Destruct-A-Thon behind Horseshoe
BattleBots Destruct-A-Thon fills an arena behind Horseshoe Las Vegas with combat robots from the BattleBots TV franchise, fighting behind protective walls while the crowd picks sides. It feels like a ballgame, not a theater. The show asks parents to bring hearing protection for children. Our BattleBots Destruct-A-Thon guide explains which fights are real.

Where: BattleBots Arena, entrance behind Horseshoe Las Vegas, center Strip. Length: 75 minutes. Ages: all ages, not suggested for babies. Best for: kids who like things that break.
The short version
Youngest kids: Popovich. One big night with dinner: Tournament of Kings. A group with mixed ages and mixed languages: Blue Man Group. Tournament of Kings also shares Excalibur with Mac King's afternoon magic show, so a matinee and a dinner show can be one building; our comparison of Penn & Teller vs Criss Angel vs Mac King covers him.
