I have flown in and out of LV several times... This airport is WAAAAY too big... Busy with all the hustle and bustle. Well, I guess that's LV for you...
I had a 1 hour layover for my flight back to SD. I looked at the screen for my gate and turns out that my gate is at the other side of the freakin' airport. I'm seriously glad that I had 1 hour to get over there!
Luckily I had time to grab a bite, which was another long trek to another area of the airport.
I did notice that there were lots of charging stations, and they were in private and quiet areas. Also slot machines are avail in various gate areas for your last min gambling itch!
