It was a great experience. The package I bought on Ctrip was a great deal, cheaper than buying it directly at the counter, and it even included a serving of takoyaki at the 58th-floor restaurant.
The scenery was also amazing. Highly recommended.
I used the Rapit and it was really convenient because the travel time to the airport was the shortest. Being able to specify a time made it easy to fit into my schedule, and being able to board immediately without waiting was efficient. Overall, it was fast and convenient, so I would like to use it again next time.
