Arguably the best thing to do in Vegas. Skip everything else that's on the way and just go to the High Roller entrance. There was no line at 11 at night and we waited with just one other group in front of us for a pod.
Offering breathtaking views with the city lit up, this is an engineering wonder. Lasts about 25 minutes.
If I could've done anything different, I personally would've brought dinner to eat while we watched.
