I agree with it needing 2 people.Loki really needs to have two people working in it. Given the nature of the ride and how it has to load at the bottom, rotate around in to place to bring the ones at the top down, and then load up again at the bottom before a cycle can start it’s an incredibly long time between cycles with just one person operating it and having to do two lots of restraint checks.
It’s taking nearly 9 minutes between cycles which makes for a very long wait.
I think Thor does 2. Thor had empty seats because they were letting people pick where to sit so you got spaces between groups. They need a second operator sending people to the next available seats to fill all the gaps.
Turnaround time for Thor was about 8 minutes which is quite slow even if the ride does hold 40 people.
