It all depends on the size of the show and the exhibition halls.

The CES is the worlds largest consumer electronics show and so makes for a pretty good example.

The CES is the worlds largest consumer electronics show and so makes for a pretty good example.

At the 2014 CES I walked a total of 33385 steps.

The first day was at the Venetian, all show floors.
Second day was the North hall
Third day was the Central hall
Last day was South Hall and the central pavilion

If you plan out how you will be covering the show floors you can do it more efficiently. I was working as press at the time and needed to cover as much ground as possible as quickly as possible and so had planned out destinations.

But if you just wander around you can easily reach 10000+ steps per day.
