You should plan to spend about one hour at the High Roller Observation Wheel in Las Vegas. The ride itself takes approximately 30 minutes to complete a full revolution, and it offers panoramic views of the city.
However, you should allow extra time for entering, exiting, and any potential waiting in line, especially during peak hours or weekends, so budgeting an hour in total is recommended. You can also visit The Linq Promenade if you are in the mood to shop, dine, or relax while you wait.
