Reception time frame..including Viennesse table

So, we're total pigs and added the Viennesse table to our reception. We're extremely big on dancing and want as much dance floor time as possible. This is why we didn't add additional dinner courses because we were told people had to be seated longer for the hot dishes to be served.

But like I said, we're greedy, so we had to get Viennesse. How long would you say they keep the table in the middle of the floor? Is this a big time eater? I'm hoping they can move it to the side for the majority of the time it's out.
