Best Place to Kill Time at the Airport: 24-Hour Fitness Yeah, in Vegas you can gamble all the way up to the jet way, but the airport terminals are not the glam'd up gaming palaces of the Strip. The airline clubrooms are okay, but a workout might be better. A gym you ask? Hey, why not give the one at McCarran Airport a go? Your sweats are in your other bag? Not a problem. Here, you can rent it all, right down to the latest look in workout footwear. And since airport check-in calls for you to come early, you've got plenty of time to give the Hamerstrength and Cybex machines a go. You may even get the chance to slip in an aerobics or kick boxing class. It's worth the $15/day fee just to use the sauna and steam. This gym is pretty standard, but it's a safe haven from airport boredom. And it'll do the body good before that long flight back home to the real world.
