I'm afraid of heights, so almost didn't go on this. Thankfully the massive scale of the buildings on the strip made things feel not quite as high as you actually are. The ride was super smooth. There were times when it took me a while to realize we were moving again.
I went early in the day so there were only 5 of us in our observation pod, giving us plenty of room to move around and clear views. I think it would be cool to go at night to see the lights, but my guess is it would also be more crowded.
There's a bar and bathrooms before you board. My advice is skip the bar. A bottle of water is $7 there, so prices are steep. The whole ride is only about 30 minutes so no real need for a cocktail, but you can book a ticket for their "happy half hour" with open bar if you feel the need.
Subtracted a star because the video commentary is super cheesy. Other than that, this was super fun.
