LAS VEGAS — There's lazy, and then there's Las Vegas lazy. Meet the latter.

In increasing numbers, Las Vegas tourists exhausted by the four miles of gluttony laid out before them are getting around on electric "mobility scooters."

Don't think trendy Vespa motorbike. Think updated wheelchair.

Forking over about $40 a day and their pride, perfectly healthy tourists are cruising around Las Vegas casinos in transportation intended for the infirm.

You don't have to take a step. You don't even have to put your drink down.

Pedestrians beware.

"It was all the walking," 27-year-old Simon Lezama said on his red Merits Pioneer 3. Lezama, a trim and fit-looking restaurant manager from Odessa, Texas, rented it on day three of his five-day vacation, "and now I can drink and drive, be responsible and save my feet."

The Las Vegas Strip is long past its easily walkable days. Casinos alone are nearly the size of two football fields. That doesn't count the hotel rooms, shopping malls, spas, convention centers, bars and restaurants.

And that's just inside. For tourists who plan to stroll from one big casino to another, there are crowds, construction sites and long stretches of sun-baked sidewalks between.

A tourist could accidentally get some exercise.

"We're seeing more and more young people just for the fact that the Strip has gotten so big, the hotels are so large," said Marcel Maritz, owner of Active Mobility, a scooter rental company whose inventory also includes wheelchairs, crutches and walkers.

Most of those using the scooters are obese, elderly or disabled. But many are young and seemingly fit.

The number of able-bodied renters has grown in the past few years to represent as much as 5 percent of Maritz's business, he said. The company, which contracts with some casinos, has a fleet of about 300 scooters.

"It makes it a lot easier for people to see everything," he said.

At full throttle the scooters open up to about 5 mph, though crowded sidewalks allow little opportunity for such speeds. They can go anywhere wheelchairs can — elevators, bars, craps tables. They come with a quick operating lesson, an instruction booklet, a horn and a basket. They advertise themselves.

"At first, I figured it was for handicapped people, but then I saw everybody was getting them. I figured I might as well, too," Lezama said.
