I just rode the world's tallest observation wheel at sunset. The 550 foot-tall High Roller has amazing views. Seeing the strip from the sky is incredible. The neon lights, the foothills and the soaring buildings are all beneath you. Best $30 experience in Las Vegas. It was fun, beautiful and very smooth. The High Roller staff was very friendly. The music & art were very retro and swingy. Pure fun.
