We'd have to run a really fast tournament in order to do doubles, which only a few people seem interested in anyway. There's no way we'd get through it. It's not up to me, but seriously, just do some friendlies. We could MAYBE do a mini tourney, but again, it's not up to me.
The tournament begins at 3:30. I can't imagine many more than 20 people showing up to this out-of-the-way/smallish/no ranked players tournament. If there are 20 players, there will be under 35 matches that need to be played, 3 or 4 of which will be best of 5.
If the tournament is run efficiently (forget friendlies, and as soon as someone wins, they report, and the TV is IMMEDIATELY filled), 35 matches is not very many if we can 4 or 5 stations.
Also, another reason that tournaments take additional time is seeding, which there will be very little of, so the singles tournament should start on time and doubles could immediately follow. And because there will be less than half as many doubles entrants: 10 or fewer teams. That's under 20 matches, and doubles usually go faster.
What time do we have to bone out of the venue by? Because I think we can definitely squeeze in doubles. (I'd be happy to help run the tournament btw if needed + I'm bringing a wii)
