reservations not needed, but you may have to wait (they just have a long line there...and a lot of it is uncovered so if you're going during the day, you'll be in the sun while you wait.)
We enjoyed the ride...and the view is outstanding.
This ride is NOT for the faint of heart, nor for anyone with a fear of heights, or vertigo, or tendency towards motion sickness. The balloon goes very high, and it is not necessarily a smooth ride up & down. Our ascent was fairly smooth though jerky for about the first 100 feet, but our landing was very bumpy and we kind of went 'round & 'round on the platform before they got the balloon exactly where it needed to be ( it was kind of like riding in the Tea Cups, only bigger, lol.) There were a couple of people on our ride that looked a bit green by the time we finally stopped moving on landing. The pilot said the rough landing happens when it's close to the "too windy" point.
