I know that macy already has tons of experience as a volunteer -- I doubt there is anything I can tell her that she does not already know.
Boston also will be my first time volunteering specifically at Worlds, and I think I understand what macy means. I too am assigned to Event Flow, and feel an extra sense of responsibility because it is Worlds. As macy described, Event Flow entails a mix of duties that will keep us on our toes, plus Worlds shifts are six+ hours, which is longer than at other events. The anticipation is different from when I know that I will be "just" ice monitoring for "just" a three- or four-hour shift at "just" Nats. Going into Worlds, a combination of a lot of excitement and some nerves for me as well.
In addition: At Four Continents in 2019 and 2023, ISU definitely had its own personnel overseeing volunteers (on top of USFS/LOC oversight). ISU wants certain things done a certain way (sometimes not the way that volunteers at Nats or even Skate America are accustomed to), and if anything, I expect ISU oversight to be even greater at Worlds.
I do not want to get into details, but by my standards (which are not as extravagant as yours), the volunteer perks for Worlds are on the generous side.
ETA:
Wait ... I hope I did not come across the wrong way. I truly believe that the primary motivation for most volunteer participation is the gratification of supporting the skaters/the event/the sport. Any perks are nice, but they are gravy.
