1 - I can definitely see the appeal and value in doing that. However, rides in Aus have had photo booths at the end of rides before for people to buy and I don’t think people do it that often (from my observations). WWF and Scooby are two of the few rides left with an actual staffed photo store at the end (and in the case of Scooby it’s not often open). Rides like SE, AA, GD, GC and EFM all used to have photo purchasing booths but no longer do. ST in peak periods has a portable printer and POS that they place under the photo viewer at the ride exit. From my perspective, isn’t it better to just buy them all at the end of the days anyways otherwise you have to carry them round all day?
2 - A lot of rides used to have this (but in sign form) at the GC parks, from what I can remember, DW has it on the Claw and GD, but that’s about it because most rides have automated wait times out the front, or A frames. Which is a much more effective way of presenting the time. And for example, it a coaster can operate with one or two trains, the printed wait times become irrelevant. It’s even ineffective on the GD because sometimes they don’t operate both gondolas. Rides like Claw, TailSpin and Shockwave it is effective on however.
3 - I definitely can see why this would be a good idea and efficient, however I find it tacky. MW used to have them at the front gate and I hated them. It was not a good first impression for a park. And the day they got rid of them was great. But putting them on rides wouldn’t be appealing. And I’d imagine staff counting isn’t any less efficient overall. The staff would still need to ask how many are in a group, do the maths of how many have gone through, etc because otherwise parties may get split.
4 - I guess with the loading procedures, the staff start at the front and work their way to the back, so if the first row is the slowest to board, the staff will end up going back and forth to make sure they’ve checked everyone. With a coaster like GL that has 4 seats, and people crossing over each other to get to the loose item storage, it can be difficult to start securing harnesses etc in some situations.
There have been times when there’s been no queue and I’ve been allowed to just continue, or harnesses are released and then re-secured because that’s how the system works (apparently).
With glasses, while I do agree, it unfortunately won’t ever happen here because of how strict the parks are with loose items. And they have to install netting over some coasters to ensure any glasses that fly off don’t hit people below, and I think netting under coasters is a horrible look.
