You laugh, but smashers are INFAMOUS for *****ing about perfectly reasonable venue fees. Some tourneys operate at a higher standard than everyone bringing a cube and a 13" TV.
If your rule set
a) makes the tourney way longer than it should be (i.e. RR pools, 3/5's, etc)
b) is crazy difficult for non veterans to understand (stage bans, striking, counterpicking)
It will be modified.
"working with you" is no items, and random stages based on the community standard. Trust me.
If you have the ability to move Gen3 and DONT move Gen3... that's a huge mistake IMO. Expecting players to take off two weekends (Fri/Mon) in a row or 10 days is beyond ridiculous.
If there's a smash stream all weekend, it'll be fan run off a cell phone or something from the BYOC area for casuals.
EVO's goal is to get your tourney run as fast and efficiently as possible so players aren't sitting around grumbling and then they can eat/enjoy themselves. They will use the exact # of setups they need to get the pools run in a certain number of 2 hour blocks of time.
Take MK9. About 300 players in 2011. They had 10 setups, running 5 pools at a time in 2 hour blocks. 19 pools total, in 4 waves. 8am, 10am, 12pm, 2pm. The winner and loser of each bracket advance to quarters at 4pm. whittled down a bit more... then at 6pm the semi finals on two stations go down to the final 8. Here's the full schedule:

During this time basically all the stations are used ONLY for the tournament. There were gaps in the 4th wave (2 stations were unused) and during the semi finals.
As you also can see, a few games run side by side. This will be even more clustered this year due to more games... but there were only two official streams last year.
I don't really expect EVO to change its methods very much. This is science to them. Attendance won't really matter, it's not like you guys are going to outdraw AE or Marvel.
The Paris does have an 80K sq ft ballroom, but I'm pretty sure they're not using all of it. Space will be a concern, but not so much as last year, for sure.
