Fly into Harry Reid International Airport (LAS)—it's the main airport and served by basically every airline. Grab an Uber or Lyft to the Strip: about 30 minutes and $20–$35 depending on traffic. No need to rent a car unless you're planning to leave the Strip.
We're obviously at the Bellagio. They gave us a link for discounted rates—use it if it helps—but honestly, pricing on the Strip fluctuates a lot. It's worth shopping around. We got better rates (and points!) by booking through one of our credit card travel portals.
The Bellagio
3600 S Las Vegas Blvd, Las Vegas, NV 89109
Staying at the Bellagio puts you five minutes from the ceremony and the fountain photos — very convenient if you want to freshen up between events.
Other great options within easy walking or Lyft distance: The Cosmopolitan, Caesars Palace, Park MGM, Vdara, and Aria are all right there.
The Strip looks short on a map and is very walkable — though it's longer than it looks (about four miles end to end). Uber and Lyft are plentiful and cheap for getting between far-apart spots. Skip the monorail — it runs behind the hotels and isn't all that convenient.
We're planning a celebration back home for everyone who couldn't make the trip — so we'll get to see you either way. More details to come.
