Most days the 1p VQ is open for an hour or more. Occassionally the VQ is open until park closing. It doesn't matter if you have the world's slowest fingers.Maybe you love getting up at the crack of dawn to play "fastest fingers" with a bunch of smartphone addicts
Your wait, once you enter the building, can be 30 - 45 minutes. VQ serves to keep the queue inside the building. It avoids long lines outside. It also limits the number of times a day you can ride it.
