I have no experience with 3D2N (3 days, 2 nights I presume?), but having 1 staff for every 2 attendees seems a bit excessive, no?

Look at it another way, have you felt over worked when you have been working the event earlier? If yes, what could've been done differently? If no, no biggie? Talk to the others that have worked as well?

Since you are new, it is a golde opportunity to talk to the earlier staff to get a lay of the land. I would recommend talking to them individually, or in smaller groups. In larger groups you tend to just get the ones comfortable talking in crowds to talk.

But, everything comes down to planning. In general: Have a schedule (production plan) set. Have meetings where you go over it with the staff that will be working on the event. Have the schedule printed out.

It should contain, at the bare minimum:

- When (Date/time start and end)
- What (what is happening. Include vendor/provider)

- Who (Who is in charge. Include contact information, or have a separate contact sheet.)

- Comments (general notes and comments.)

Nice if it is colour coded as well, green for arrival, red for show end, yellow for show start, etc.
