Walking the Strip
Las Vegas Boulevard between the airport end and downtown covers a few miles, and individual resorts are enormous — walking from the lobby of one mega-resort to the casino floor of its neighbour can take fifteen minutes on its own before you've left the property. Wear shoes you can actually walk in; heels and the Strip's long, climate-controlled indoor corridors don't mix well over a full day.
The monorail and free trams
The Las Vegas Monorail runs along the east side of the Strip and connects a string of major resorts and the convention center, which is genuinely useful if your hotel and your dinner reservation happen to sit at opposite ends of its route. Several neighbouring resort groups also run free connector trams between their own properties — handy, but only along that specific stretch.
Rideshare and taxis
Uber and Lyft cover the whole valley and are the easiest way to cross longer distances — say, Strip to downtown Fremont Street, or out to an off-Strip restaurant. Pickup zones at big resorts are usually well marked but can involve a short walk from wherever you actually are inside the building; budget a few extra minutes at very large properties.
Renting a car
Skip it if you're staying entirely on the Strip — parking, traffic and resort fees make a car more hassle than help. Rent one only if day trips (Red Rock Canyon, Hoover Dam, the Grand Canyon) are on your itinerary, and consider picking up the car on the day you actually need it rather than for your whole stay.
