Branded Belt
The same 8 ft belt carrying your wording or your mark. Where the line is long, it is the surface people look at most.
It suits an event where the queue is part of the experience — a launch, a sponsor activation, a members' entrance. It makes a poor general-purpose belt, because wording specific enough to be worth printing stops being usable at the next event.
Printing has a lead time, so this is the one item where the answer depends on when you ask. Raise it as soon as you have artwork and take blank belts for the rest of the run.
